so my car doesnt go over 4500 rpms and only has 14psi so i was wondering if anyone has had tohught that possibly my car went into limp mode for some reason? i dont have KR either so i was wondering also is it possible my fuel pump just is gong out as well

Are you monitoring your DI fuel pressure with the Dashhawk? That will tell you if it's a fuel pump issue. Kind of unlikely that a dying fuel pump would limit the car to 4500rpm. It would just cut out when the pump was stressed, not at a specific rpm.

Have you rest your ECU by pulling the negative battery cable for a couple minutes? Any CEL? Any codes that the Dashhawk can see?

If that doesn't work you might try reflashing your map as that almost sounds like Valet mode.

ino cel and havent reflashed it proably ry the battery idea later just been in denver lately with buddies

could it also just be a bad tune? if it doesnt work

Not likely. I would just try reflashing your tune again. See what happens then.

yeah all my fuel trims and pressure is fine no kr and i reset the ecu and reflashed and the ar is still having the same problem

Have a SRI on it?

Will it go above 4500rpm free-revving while stopped? Or without much load on the car? Or is it only stopping you at 4500rpm when you are WOT?

i am fully bolted on the car well over 10k on the car

and eric my car in 1st gear wont go over 4500 and when i shift to 2nd it will but it struggles to go over that if i am in wot or driving regular it will not go over 4500 rpms i dont think that my launch control ****ed my ecu yuyp though because tahts what my launch control is set up as well though

I bet you anything the VSL (vehicle speed limiter) is messed up in your launch control settings. Your VSL should be like 12. If you have it too high, it won't turn off the lower rev limiter until you get above the MPH you have set for your VSL. So if you never get to that speed, it will keep you under that rpm indefinitely.

Try just changing your settings to these in ATR and reflashing and seeing what happens.

FFS Rev Limit: 5300
LC Rev limit: 2800
VSL: 10 (mph)

would that get messed up well over month and half since my tune though?

Did you just play with the launch control settings? This doesn't actually have anything to do with the tune itself. It's a launch control thing.

nick set it up on my car....but maybe i have a boost leak or even my ecu is just messed up i hav eno clue i switched the map and it didnt work to one of the ap maps

Could your car drive on the stock calibration? If so, try uninstallting the AP and see if it works. That way you can determine if you have a calibration/tune issue or another problem.
