Yep. Here I am. Twinskrewd from the other forum Blownford here. And like I said there Troyer is a great guy and a wealth of info but these vaccum bypasses combined with drive by wire are his achilles heel. JDM for the win on the Whipple. They will be doing my retune.
Troyer can tune the Roushcharger all day long with the electric bypass. And he has written me a safe and powerful tune for my truck but the throttle surge issues when cold and the bog down at the 1/8 mile traps are not going away. I have given up on him for that. He needs the truck there for multiple days to figure it out or so he says and I'm not driving 6hrs one way and staying in a motel for 2-3 nights for it. And after talking to numerous others who have had the same issue it never gets corrected. For that money I can have JDM write tunes. JDM has zero complaints. They use SCT and Jim Sr and Jr have impressed me so far. Can't wait to do business with them.
Also nothing wrong with an email tune. Troyer and JDM are both capable of writing good tunes. Just be prepared for throttle surging if you go with Troyer. Also you can go to a local dyno with your tune and data log with the SCT the. Send the results to JDM and they will make the tweaks for free to the tune just as they would on their dyno.

good info i was talking with Twinskrewd on the other forum is well he did recommend JDM so i think thats the way im going. He also recommend going to 39 or 42lb injectors now i just got my supercharger installed but if i were to cahnge the injectors my self do you have to remove the blower again it looks like i dont have to but im not sure....i wish i had done the injectors to begin with when eveything was off now just cost more time and money now ...never ending.

Nice I"ll for sure change my injectors, doesn't look that hard call Jim at jdm and get the tune sent to me re flash my PCM approximate hp gain between new tune and new injectors you have a rough guess? I assume the drivability will be way more beneficial

Correct. The driveabilty will be vastly improved as will the safety factor. Custom tune and having the correct injectors should net you 25-35hp at the wheels. You should see 400rwhp. Or at least somewhere in that range. The 26" wheels may hurt you some depending on the weight of that wheel/tire combo as will the awd. So it will be interesting to see what you end up with when you do a dyno run or a trip down the drag strip. You will not be disappointed thats for sure.

And changing rims 
(sorry)
Why not do a street tune? Dyno tunes are only valuable if you are obsessed with #s. A street tune will ensure the truck performs best on the street, where you will be using it. I find I have to change timing and fuel slightly from a dyno to the street.
It takes a little longer, but it's real world.

As for having to make changes to your timing and fuel for the street verses the dyno... Sorry but someone wasted your time. You should be tuning on the dyno with the timing, a/f', and loads factored in that you would use or encounter on the street. Otherwise you just have inflated hp/tq numbers that are a lye and can't be backed up at the strip. Anybody can run more timing on the dyno and leaner a/f's to make a dyno sheet good.
Lastly any professional tuner not "tooner" is going to test drive the car with you and make any desired changes you as the driver want. For example, shift points and firmness. JDM and Troyer both for example offer free changes for life to your tune so if there is something you don't like or change your mind about you can.

Really a dyno tune is only good for chasing numbers??? That has to be one of the dumbest or one of the most uninformed things I've ever heard. A dyno can be an invaluable tool in tuning. Thats why car manufactures and race teams use them worldwide. Most good tuners rarely even click on the screen with the hp and torque readings until the last run or two unless of course you ask them to. They're to busy combing through all the data collected on runs and making the needed corrections to the tune. They want your dyno numbers to reflect what you are driving away with.

If you dont know what you're talking about, keep it clean. You dont have to be a rear end and disrespectful because I disagree. Dont have much forum manners do you?
How many vehicles have YOU personally tuned? I'm speaking from PERSONAL experience, you're repeating what your "tooner" buddies have told you . I think I may have done just a few more tunes, so I actually DO know of which I speak. I had orinially inserted the rwhp#s on my persoanl cars , both NA and blown, just to put your trucks #s in prespective, but that wouldnt be cool and nobody here cares and Im not going to turn this into a Pi _ _ -ng contest. They are different motors so it is irrelavant, but needless to say, they make crazy #s and both were tuned 100% by me, on the street/strip and TWEAKED on the dyno FOR NUMBER INFO ONLY!!
Of course the dyno is a valuable tool to get you close AT WOT. Then those RACE teams hit the track and make MORE changes. If all you do with your truck is race, get close on the dyno and then hit the strip and log for KR and AFR and go at it. If you drive it 90% on the street, a dyno is ALMOST worthless (except to get some #s for those dyno queens to do some bench racing, and post them on their forum sig
) since most tuners ONLY TUNE WOT! If you have a TUNER that tunes part throtle, then he is a rarety and one that understands tuning. I know at LEAST a dozen tuners and ONE of them (in Atlanta) does part throttle tunes on his dyno. (and charges a lot more)"loads factored in that you would use or encounter on the street"...... Or you could just drive on the street while you log.
In order to get tables like VE and MAF, timing tables, of idle shift points, etc,correct (VE not necessary on a ford)you MUST log on the street at various rpms(tuning school shows you how btw) then smooth the tables and repeat. (It is a BALL to tune them on the street 
)After a few runs, the vehicle will be PERFECT and run like you never imagined it could. SUMMARY;
Guess what, some people are going to disagree with you - get used to it and quit being so rude
For braggin rights and to save some time (and tickets) tuning WOT, use a dyno. Then tweak on the street/strip
For a GREAT driving vehicle, tune on the street.
I hope I didnt offend anyone else with this
but I dont care much for members, no matter how knowlegable, that think there's only one way to do things. I'm new on this forum, and am trying to learn about Ford Trucks, but I've modded vehicles for 30 years, am members of 5 forums, and have found that NOBODY knows everything, and tolerance of others opinions is necessary in a forum's funtion.
