I only paid $700 for my Wagner from Franchi, that's half the price of the Bell. I am a heavy tower not a drag racer so I can live with a little less performance for a lot less money.
To the OP or anybody else having trouble getting your tunes- Post your info in the customer section on the SSI forum and call Shawn. Before you know it you will have T5.

I am not even a drag racer, I just spend to much money on cars

I have the ATP CAC. Which is better than stock but maybe not as good as the Wagner or Bell.
IDK, really only one way to tell just how much difference between the three would be someone with deep pockets to buy all three and get on the dyno. With the same truck do three pulls on each(hot lap) and go from there. With HP, TQ and IAT numbers on each.
Who's game?

A dyno run for the Wagner showed 5rwhp and 50rw ftlbs of torque

Not to throw facts around in here but that has more to do with less pumping losses. The Wagner just like the Garrett and SSI/Bell are more efficient and have less of a pressure drop which could easily make those numbers over the stock unit.

What do you look for when forming your opinion on a tune being safe? I have tuned a couple of my own vehicles using Advantage 3 based PRP. I have datalogged my SSI tunes to death and still do daily when I drive the truck. The SSI tune even having 6 more pounds of boost is safer than the stock tune that came on my truck. I have hours of datalogs but to post them on here for you to form your own opinion is ridiculous. If you are so worried about the tunes and want to be the guy that can save the world with your outstanding tuning knowledge please by all means pay for a set of tunes and datalog them yourself.
I don't know why this community is so against "data logs" from tuners being shown. Another gripe I have is the idea that these tunes from custom tuners aren't canned. The tuners aren't making you a custom tune everytime they get a new customer, they are building the tune off another truck that they did a custom tune. Then they usually pull some timings, slightly lower the boost, and richen up the fuel table to ensure it's safe for every truck. They are using the same tune they gave the last guy and every other guy. A custum tune REQUIRES datalogging and then reading the data, changing the data to get the most of the individual vehicle.
I use to do some of my own tuning back on EVO's a couple years ago, so i have a small grasp on some thing you can do to make a tune feel fast and feel awesome. With that being said, having the waste gate immediately close to like 70% or more with a light touch of the throttle (which is what it feels like on my working tune from Shawn) it creates huge amount of instantaneous torque, giving you that SNAPPY feeling. That Snappy feeling is just murder on your drive train over time. It also increases cylinder head pressure along with added heat and unnecessary increased drag on your turbos. All this leads to decreased durability of your engine and turbos. In my opinion, I just don't like the massive amount of boost under light throttle operation...that's suppose to happen under WOT! Again all of this is my opinion about the tune. Some people just want all out power and torque throughout all RPM's and loads. If you want uncontrolled unrefined power, SSI tunes are probably for you. They do feel incredibly fast, but I don't think a .25-.5 1/4 times change is worth it especially on a daily driver 6000 lbs truck.

I am not sure how to approach this with out sounding like an *** but I will give it a try. Just going to state facts about what I know and not speculation like others do.
Firstly, you can half *** build a timing map from a datalog. The datalog can show you many things that can be used to help build maps. They will not be 100% but can be used as a starting point. You can get tip in spark and then trend the spark table to your final spark under WOT. It again will not be 100% but can get you in the ball park and this is why no tuners want their datalogs on an open forum.
Secondly, if you do what is asked of you then the SSI Tune is as good as a custom tune to a point. You are asked to datalog certain PID's and send them in. They will be checked out and if the tune needs some tweaking it will be done and an updated one will be sent to you. You can do this as many times as you like. So that is not a "Canned Tune". Many tuners do this, it's called "Remote Tuning" and is a big thing as not all people are close to trusted tuners. Before I started tuning my Mustang I did this a couple times and had great success with it. This was tuning on a 1000hp car from a guy that was 2,500 miles away from me, albeit it was on a rented dyno and not the street but everything worked great. The SCT Tune that comes on the devices are a true "Canned Tune" and are a little better than the tunes you are given as "Base Files" in the SCT Tuning software. I could not get my bone stock 2004 Lightning to run with the SCT provided "Base Map" that was included in the Pro Racer Package. I had to go in and change many things to get it to run. When I installed the Whipple on it the injector, IAC, and many other things still had to be tweaked as the "Base Files" were not 100% ready to load and drive.
As far as the SSI specific tune you are commenting on. Well I will not get into much detail as I have promised to not divulge anything I know about them. So I will say that the throttle is made a bit touchier and can be changed back closer to stock if you ask for it. I know because I did ask for it and had the updated tune in my inbox within an hour. The wastegate control is not rocket science and is manipulated to help with the off idle boost. It is close to stock settings but changed to help with low end, low throttle input torque. This makes the truck feel lighter as torque is what gets these 6000lbs trucks moving.
As far as snappy feeling tearing up your drivetrain. Well the quicker shifts actually decrease transmission temperature. Slipping through the gears makes heat and firm shifts reduces the slip causing less heat to build up. The cylinder head pressure on a boosted engine is higher than normal anyway. You are stuffing another 15psi (1st 14.7psi being the atmosphere) into the engine which only makes more cylinder pressure and more heat. You are not tearing up anything on your truck with quicker shifts, if they are violent shifts that make loud clunks due to it backlashing the driveshaft and rear end then you could cause premature wear on the drivetrain. This hasn't been the case with any of the tunes I have tried. As far as increased drag on your turbos... The BOV stays vented to an extent until you are at WOT. I can hear them open and close through my intake, this relieves pressure on the turbos when not needing full boost.
Again not trying to be confrontational but I felt I needed to express my opinion on this with as many facts as I could.

If your happy then OK. I'm just saying that based on whom owns SSI tunes and previously had MPT they don't use MPT anymore. The issues with you tune can be remedied I'm sure. But again enjoy your tune I just think if you got the SSI tune from Shawn and let him fix it you would be running that one.

I've been researching tunes and attempting to find the best deal. This question may stir up a lot of stuff but is SSI tune worth the price? $175 compared to 5star $100 or $160 for two or MPT $100. I currently have a canned SCT tune. I have AFE Stage 1 CAI, custom 3" Banks exhaust. I'm installing catless off road down pipe this week so I need a custom tune. I'm running stock wheels on 35x12.50x18 Nitto Grapplers. I'm looking for more power and of course fuel economy. Anybody running a similar set up can tell me is the SSI worth the extra money? What kind of fuel mileage are you getting?
