Vette LT4 tune vs Camaro LT1 tune i have a 97 Camaro SS. it was a LT1 from factory and i am in the process of converting to a LT4 using ported heads, a ported LT4 intake, and TB. i am also adding a Comp Cam XFi 468 grind camshaft, electric water pump and 39 lb injectors. i am not going to have time to get it properly tuned until after G13 in Atl. would it be safe to run on a stock LT4 Vette tune until i get back (with the changes for t-stat, o2's, !egr, 1a.i.r., and injector sizing)? i will wind up putting approx 600 miles on the car before i can get it on the dyno. i can't find a LT4 Camaro tune to start with (guessing due to their rareness). should i stick with the LT1 tune or use the LT4?

the 468 is similar to the cc306, but has more lift. i am going to do a custom tune, but i'm not going to have time to do it till i get back.
