Getting re-tuned Friday at AVT Performance

[GK_crewchief]

Well a few months back I installed my JLP Comp R 3" exhaust kit but I was too busy with work to get down to Arthur Todd's shop AVT Performance in Conway,SC and have him re-tune my truck for the exhaust, so this Friday morning I am taking the trip down there and he is going to re-tune the truck. I'm not sure if I will see any kind of big gains, but the engine is sure breathing a lot better than before with my old exhaust and headers. My last dyno tune numbers were

Street Tune: 605HP/623TQ at 15psi 14* timing 93oct. Fuel with 4lb lower/3.5" upper Run Conditions 72*F 36% Humidity

Race Tune: 639HP/693TQ at 19psi 18* timing VP C16 Race Fuel with 4lb lower/3" upper Run Conditions 83*F 66% Humidity

I'll post up some new numbers when I get back Friday.

I'm still thinking about selling it.. just wanted to get the truck tuned again.

Subscribing.
Dont sell it, you'll regret it.
I'm glad I'm going to see some before and after numbers on the comp r exhaust.

UPDATE:

The truck made 621hp/650tq with timing set at 14 degrees and 93 octane on a Street Tune! We didn't do a C16 race tune pull and he checked all the information in my current Race Tune and he said I will be fine. But I know those numbers would have jumped up nicely if we did a C16 fuel dyno pull!!! Thanks Arthur!

The difference between my last dyno numbers and new ones with the JLP Comp R exhaust were 16HP/27RWTQ. Not too bad I guess...

Your A/F is spot on, looks like you found a great tuner.

Thanks. Oh yeah, Arthur is a veteran in the GEN II Lightning scene.... kick ass tuner and very knowledgeable guy.

What was your old exhaust setup? You mentioned headers, did you have a full exhaust already?
