We base lined the car prior to any tuning changes. The only difference being the 18" Z06 wheels with 345 M&H tires v's the stock 20's. I feel the weight has to be similar.
today it's 55 and 91% humidity due to the rain 593 rwhp today
previous was 581 rwhp 566 rwhp today
previous was 530 rwtq (due to a little tire spin since run prior was 550) new #'s @ same 10 psi & 100 octane
max timing was originally 15 and now is 24
We will shoot for the 10 sec ET with 93 octane and use this tune as backup
