6.0 strategy tuning question

[cjg454ss]

Would like to first say its good to be home, i was in a chevy for the past 5 years and missed my 6.0

searched all night and can not figure it out.

i had a 06 6.0 f350 4x2 5 years ago, i also had the sct loaded with innovate tunes. sold the truck and kept the tuner.

last week i bought another 06 f250 6.0, i pulled the tuner out and checked the strategy. the f250 had the most current, VXCF9, the customer tunes from my older truck has VXCF1.

I loaded the tunes last night and the truck seems to run great. shifts nice and the power is how i remember it. and no more turbo sweep at idle. i ran the extreme street. only thing i notice was the boost was at 30psi. i couldnt remember what it should be on that tune. my stock loaded tunes would do 20psi and thats it.

any thoughs or concerns, next i want to look at a PHP ficm tuner

Bone stock my 2007 hit's 28 psi.

the strategy i dont think matters, the tune writer will select what they like best. as far as boost goes, if it is not a mechanical gauge, it wont read correct, they also write in boost fooling so an obd ii sourced signal wont be correct.

cool thanks for the headsup, i have my snow kit installed also, 50/50 water meth, anyone run these with dyno results? i have a single small nozzle, 625ml i believe.

Yeah as long as the same base strategy is present it should run just fine. Most tune writers will write their files based off of an older strategy such as yours. For instance the 2005-2007 trucks use a VXC series strategy and 2004.5 trucks use a VXB series strategy and the 2003's use a VXA strategy. The "1" or "9" in your case is negligible as those are just versions of the same strategy, BUT the older versions run better and that is why tune writers base their custom files off of the earlier version of the strategy.

I have the vxb srategy an would liek to get the vxa strategy eventually once my new turbo is in... Heard there is a big difference?

That's not entirely true Bryan. For instance Matt at Gearhead writes his tunes using the VXCF9 strategy. It all depends. I am running on a VXCF4.

The VXA strategy is for the 03 trucks and I don't believe it would run right on your truck Greg.

Mitch what I meant was that in most scenarios the older versions of the strategies run better. I too am running a VXCF4 strategy for tunes but my stock strategy is the VXCF9 strategy.

[PGreenSVT]

Yeah, I had mine rolled back to the VXCF4 so that is my strategy even if I load my stock tune.

Why did you do that Mitch? When I spoke with Bill he said that if you have your tunes written off of a specific strategy there is no need for a PCM rollback unless you plan on running the stock file.
