stock LT1, stock LT4 or slightly modded LT4
i should have my LT4 conversion finished tomorrow, but i don't have time to get it on the dyno and have a proper tune before i leave to go to Atl. for G13. this is what's done to the car...... ported LT4 heads, ported LT4 intake, Comp Cams XFi 468 cam, roller t-chain, 1.6 roller rockers, 42lb injectors, long tubes, ORY, !EGR, !A.I.R., 34% underdrive pulley, electric waterpump, aluminum flywheel, lightened LT4 pressure plate, SLP 2otl exhaust, 160* t-stat, 1LE driveshaft with 3.42s in the rear. right now the tune is stock except for codes removed for o2's, egr, air, skip shift, and fans changed for 160* t-stat. i have a stock LT4 tune, and a tune for a LT4 with a CC306 cam. i have to drive the car ~800 miles before i can get it on the dyno. what tune would i b safest to run?
