If you can't go past 3,000 rpms that means the car is running in limp mode. It could have to do with air/fuel ratios or the timing is way off.

If you can't go past 3,000 rpms that means the car is running in limp mode. It could have to do with air/fuel ratios or the timing is way off. Limp Mode is a protection that the ECU uses when the car is running too rich or too lean to minimize the chance of detonation and blowing up the motor. It also will happen when oil temps get too high or the MAF sensor becomes contaminated since it can't get a proper voltage.
Please take it to a competent tuner and try staying out of boost until the issue is fixed.
