Are you still tune on UpRev if so you need to make the jump EcuTek....wait you will have to switch because Seb doesn't do UpRev on 370zs any more lol! Also, you should get the Z1 anti-fuel starvation kit as well. My car would fuel starve at the track after 5 gallons of fuel would bun off. With the kit I ran the tank down to 1/4 with no issues. I didn't try going any lower.
