I cant decide on which one to get. Its a tie between the diablo predator and the jet performance tuner. The jet is about 70 bucks cheaper but it cant do air fuel adjustments for on the silverado version. I will be puttin on pacesetter long tubes along with the tuner. I already have a k&n fipk and true dual exhaust from the manifolds. Will i need the fuel adjustments for the headers or will the jet be ok and save me some money?

 

What year of truck is this stuff for? I have a predator for sale but it's only good on 2003 stuff.

If you really want a handheld I would go with the predator over the jet for sure, most people will tell you that a custom tune will benefit you more than any handheld.

 

my truck is a 2000 with the 5.3 liter and z71

 

i see in your sig you have a tt3000 and flt lv4. what are they?

 

Bo Duke01,
With the mods you have listed I can't believe you dont have a custom tune, how does your truck run?
The TT3000 is a 3000 rpm stalled torque converter
The FLT is a transmission

edit: Oh, i see the mods are for the T/A

 

I wonder does the T/A have a custom tune or not? If so, why not take the truck to the same place the T/A was tuned? Custom tuning is the best option. Handheld tunes can't possibly get the best results, probably not even close.

 

that t/a is dead. i probably should take time to change my signature. i had that t/a when i lived in kansas city and yes it did have a custom dyno tune done for a very high price. But since then i have moved to wayne nebraska and there isnt any tuner around for a long ways. like 300 miles. and i figure that with just headers, true dual exhaust and a cai i would just need a handheld.

 

oh and it has a 160 t stat.

 

Parish and his crew are from Omaha. Looks like its around 100miles from you. Could probable get one of them guys to help you get a good steet tune.

 

but with my minimal mods do you think that that is neccessary?
