Have the Superchip micro-tuner and FTVB all installed and have done some playing around and the combo is AWESOME! It shifts so much faster and with more pressure. I can now chirp second! If anyone wants a mod, this is one of the best ones to get! Mike T and his Crew did a great job helping me out and answering all kinds of questions, even ones about diablo. Anyway, the track is closed till Late Feb, so will post times when it opens up.

 

i just dynoed my truck- my diablo chip helped my truck 03 5.4 4x4 go from 188 rwhp to 220 rwhp- flipped the switch for the dyno runs-phil

 

What was the torque?

JMC

 

300 ft lbs
got a problem- that run was in drive- 4k rpms was peak #'s
tuning guy said there is possible a restriction in the cats- only 8k miles on truck- in wouldn't put the rollers past 4300 rpms- in 2nd it would spin to redline-5300 or that the base pcm tuning is bad?
i took it back to dealer and showed them that in fact something is wrong aster 4k- even on highway romp- will not pull more than 4300 in drive- truck has 8800 miles - 8 months old- i know for fact she used to shidft into od around 5k rpms- so have ya ever heard of cats going bad so soon?
