Improve. It all depends who did your porting and how well of a job they did. Seb’s tuning is on point, but I have a knock issue. Don’t know if it’s a false knock or real knock, we did over 150 logs with race gas twice still kept knocking which I believe is false knock, but to be on the safe side we kept the timing down. But I ran with another Z making over 340 and we are neck and neck. I never went back on the dyno after the tune. Hey if you’re interested me and SS firehawk signed up for track day at Sebring October 7th through chin motorsports.
