Just 4th gear. So what do I need to change in my programming?

What does your fueling look like when this happens? Wideband numbers would be great but I know not many guys have one but they really do help out. As mentioned above 4th has a very high load on the engine, especially pushing a car into the wind at 130+ mph. Me and several other local guys used to do this often and I dont know of anyone that would have KR shoot up at all like that. Does the 15 deg KR stay there or was this only at the shift? Do you have a tuner or are you using a stock/shelp tune pcm?

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.
