I have a 2007 F150 with the 5.4. I am currently looking to see what the best tuner is for getting preformance. I am going to be putting an Airade intake, and a cat back flowmaster on my truck when I get the Tuner. Any suggestions?

 

SCT X3, SF3, Livewire, etc. Or if you wait a bit, the new X4 is coming.

www.sctflash.com

use the above hardware to deliver custom calibrations from:

VMP, PHP, Troyer, MPT, 5Star ... and others ...

Please be advised that 'Fartmaster' should never be used in the same sentence as 'Performance'. They are not a perf muffler. Sorry.

And - you will REQUIRE a custom tune to run that intake safely. Do NOT install it until you have the tuning in hand.

good luck

 

MGD what is your beef with Flowmaster? Every post I have seen you are bashing them. Its a matter of opinion, so if someone wants a Flowmaster by all means let them do what they wish, you don't have to like them however some people do. And you aren't going to get much "performance" from an exhaust setup anyway.

 

I've been looking at the Edge CTS, would an SCT TS be better? Would an x4 be even better? Seriously, other than adding a cool-looking screen that tells you stuff, how different can a piece of hardware that flashes the firmware on your ECU be?

Somebody please straighten this out for me, it's confusing as all hell.

 

Hi.

You have a CAI/WAI - hence you need a device that can deliver custom tuning.

Edge CS/CTS cannot be custom-tuned by PHP - and Edge is to blame. So that unit is off the table for you.

The exact SCT device model only matters for it's secific extra features - they ALL are just delivery mechanisms to get the custom calibrations into yer PCM.

Pick one you like, at a price-point that you can handle, pick a vendor and call them to order. Both device & tunes from one place.

 

Every post? - you exaggerate.

Simply put - they hide junk science and engineering behind a name that is decades old to mislead everyone. They are the ones making performance claims. It's a solid well-documented fact that baffling kills velocity- the baffling is there to induce specific sound characteristics, nothing more.

Buy it for sound? Sure, fine with me - but don't peddle it as a performance-enhancer, because it does not even work to PRESERVE what existing perf you already had - e.g negative impact on low-end torque.

It is a POS as a go-fast goodie. They are not even made that well! And that is MY opinion. Based upon observable facts as i have seen them.

IF you don't like reading my posts may I suggest the Ignore list.

MGD out.

 

I was running an edge Cts on my 5.4 but switched to the SCT with 5start custom tune (don't recommend them). I'll be getting a tune from MPT shortly. Personal opinion would be get the SCT and a custom tune. Waaaaaay better for ur truck!

 

you can get an evolution customed tuned ... and a CAI on an07 does not require a custom tune to run...

 

Sorry - not gonna aruge, but I disagree. You can't make that blanket statement without measuring open loop A/F's for the intake in question.

The tuning shops are STILL writing MAF transfer functions for even current-model trucks - an '07 is not immune. NO vehicle that places a slot-style MAF into a non-dedicated venturi (think the 1997-2003 trucks which had their own integrated venturi assembly) is immune. It's a Primary sensor - it's sampling calibration must be correct.

Roto-molded plastic intakes can exhibit a +/- 10% variation in deviation from the reference design - if that occurs in the MAF region, it will also cause issues.

That's why datalogging is so important - it allows the tunin' feller to address specific vehicle variations. Almost every truck is slightly different - apart form the hundreds of differnt strategy codes used.

I'v discussed this at length with several tuners - it's not news.

Lastly - it's a simple test (one I did long ago, since I didn't believe this either). Datalog the stock calibration, with OEM intake. Clear adaptive, install aftermarket intake, datalog again. Compare Open loop A/F data. On my truck, it showed a gross lean condition ( but no CEL ), as the factory tuning now did not have a MAF tranfser function to match the sampling data the MAF was outputting. And once again, after the corrected tuning was flashed, did it again. The curve was perfect and safe. You do need access to a wideband though (which i own).

Again - not looking to joust - this is from my personal experience over the last 10+ years working with custom tuning.

Switching topics -

Evo (15051) can be custom-tuned, but CS/CTS cannot ( unless you were 'grandfathered' ) - it's on PHP's website.

OP - what was wrong with your 5Star tuning? Did you give them a chance to correct it? Did you datalog?

good luck

 

I didn't need one on my 06 either. I assume you are referring to the dreaded "running lean" issue?
