Need some help picking my performance chip.
 
Im interested in getting a performance chip for my truck, but I'm not sure which one I should go with. Im looking for the best upgrade. Anyone know which is the best?

the best for the 5.7L HEMI is the Diablosport predator. It's the most mod-able and has great pre-sets for the HEMI. Works best when combined with a CAI and exhaust.

I agree with CdnoilRam , Diablosport is probably the best out there .

What is there the probelms that I have been hearing about diablo and it wreaking trannies?

Mostly the problems are due to users who think they know what they are doing when setting shift points at WOT. They are trying to shift as close to, or above, redline.

What they don't realize is that by the time the transmission control module makes the gear change, they are up against the rev limiter and the engine is cutting out...creating multiple, high level torque shocks to the transmission and maxing out line pressures.

The best way to set shift points at WOT with a Predator is to be at least 200 RPM below redline, then test. If you are still hitting the rev limiter, back off in 50 rpm increments. The reason it hits the limiter is that it takes a second or two for the TCM to signal a shift and by then, with the shift point set too close to the rev limit, it's already past redline before it shifts. Ya gotta give it a little room to work.

Wow, Maddog couldnt have put it better.....Predator can change shift points, not so much firmness like a shift kit

I have an 03 Hemi, Should I still go with Predator? I hear they don't have the update needed.

Thanks
