Hey all,
Brand new user here...never tuned before, and just plugged in the HPT unit a few mins before posting this! The car is new to me, but already had some mods done, and was tuned by a shop in SoCal via HPTuner. I'm wondering if there's any room for tweaking things at all as I begin to learn how this all works. I also run higher octane fuel than what it was tuned for, and opened up the exhaust slightly. I'll try to post all relevant info below. If I forget anything, let me know and I will get you the info quickly. Thank you in advance!
Car:
2003 Corvette Z06
Engine:
Gen4 LS3 (built by American Heritage Performance)
Mods/Hardware:
91 octane fuel (CA car)
GMPP ported heads, 275cc
BTR dual valve springs, Ti retainers (.660")
Comp cam (226/238, .627"/.627", 113 LSA)
Stock LS3 intake, ported and radius rod-modded
Stock LS2 throttle body, ported to 92mm (Peak Speed Shop)
AR long tubes, gutted cats (1 3/4")
Stock C5Z axle-back
Stock C6 LS7 MAF and air intake/bridge with K&N
Current Tune:
For the above mods/fuel, tune by Church Auto in Wilmington, CA
Dyno was 493whp/463wtq
(tune attached below)
...as I said, the changes since purchasing are very minor, but I want to tinker and learn how the changes affect things...
Changes since purchasing:
1) I run 94 octane fuel instead of the previous 91, so I am wondering if I can bump the timing advance a little?
2) Changed the axle-back exhaust to freer-flowing, straight-through "bullet" style mufflers
*3) Not done yet, BUT, I have purchased a full 4" air intake with a 4" MAF tube, and I am looking for info on how to adjust the MAF tables for the new tube*
...that's about it! Please let me know if this tune looks typical, and/or if there are any advisable changes for the new fuel octane or anything else. Thanks so much!
