Set the limiter to 120MPH.

Okay, I'm sorry.

Uh. It was like 2* maybe and then the shift happened and it shot up to 6, 12, and then got up to 15 in the frames. I was scannnig but for some reason it didnt save it. My fuel injectors are maxed out. I saw 23.01 on the IPW's. My fuel trims are staying around .78 when I get in it though and it dont move around too much. So I was just looking at the program I have in there and it shows 130 on the 3-4 perf shift. Is that what i need to change. Also, Do I need to raise the RPM limiter or is that for regular drivng?

If your injectors are running that high of IPWs I would upgrade the injectors and retune the car before playing up at those speeds again! Without a scan its hard to see what is going on.

yeah i wish it would have saved but, ill get another one. I seen the 23.01 at the top of 3rd gear with almost 11000 HZ on the MAF. I know I need injectors and was thinking about those new SDD Fatman rails too. But how do I tune to go faster.
