[got paint?]

I just went to bought a new predator,but it won't load because the truck already has a tune, are there any options other than going to the dealer for a re-flash? BTW, stock 02/mag exhaust /k+n Thanks for any help!

can you get in touch with the previous owner

[got paint?]

Nope,tried that already

[fepony]

Get ahold of JDM or some other SV and see what he says.

sure it has a tune loaded or is it a chip inserted into the PCM

Thank you sir ,that's what it was!!!

[bgstew6]

nice

Now why did you have a chip? what were/are the mods on the truck...are you sure you dont have a smaller upper or larger lower? or anything else that would warrant a chip

Sorry, been busy for a few days, I bought my truck through a friend from the 2nd owner who only had it for a year and 43 mi ! , he couldn't afford it, I looked at it,w/46k, all I saw was a k+n/ exhaust looks like it was never touched as do the bolts on the lower pulley, the upper def. looks stock, I still have a lightning upper from mine,and its smaller, so I don't know why, I will say , w/ the chip it shifted like it had a valve body, and was horrible on fuel, I have a 93 predator tune in it now,shifts stock, still sucks on gas, I guess because these are heavy?

LOL hope you didnt buy your for MPG cause you aint gonna get it.

THe chip at least had the line pressure upped in it...hence the stiffer shifts.

and yuo did put the Perfomance tune in and not the pulley tune correct?

Yep,93 perf tune, I have a 6lb for it, I can't imagine how bad the gas is going to be then, I would love to know what the chip had the line pres. at, it shifts no where near as good, and I up it a small amount w/ the predator

You can get a FTVB for your trans and it will shift very good and won't damage your trans like putting more line pressure will. Several SV's on here sell them.
