Just got re-tuned at CFT last night Rolo is the man. I was there for about 4 hours on the dyno tunning and tweaking and hit 648whp and 580 tq, on my great GT35R from AMS, MY AMS 2.3 stroker and all the bolt on's but the great thing about it is that this was on a stock head!!!!!!!!!!! I have a inner cooler sprayer that I'm going to fill up and go back with a ignition boxs for more spark and i hope i hit 700+ whp on a stock head. thanks CFT, AMS for all The great Parts and Ride Of Daytona for the Great deals and great Installs by the installer Shane
