I have a 4.3 reg cab. yeah its the smallest motor on the boards, and probably the slowest, but he made my truck come alive and i dropped 7 tenths off my quarter. as stated before, he is a very intelligent young man. i wouldnt go with anything but his stuff.

i like my tune from allen. with full bolt ons i went 13.80 in the 1/4 in an ecsb 5.3 on the stock cam. looking for 13.5 next time out. my truck isnt the norm though. as far as anyone knows im the only ecsb 5.3 silverado to hit 13's on the stock cam/heads with no forced induction or nitrous. i wouldnt go with anyone but allen :thumb:
