what is the best setting for a/f mixture after installing long tubes..?

LS1-450

14.6:1 is considered stoich. for cruising. 12.8-13.0:1 for WOT. IMO, 13.0 is a bit agressive & most shoot for 12.8:1. Also, if looking for better gas mileage, 15.5:1 under normal driving conditions is OK. I have long tubes & these ratios work great on my H/C/I set-up.
