Crazy Problem

[Mike98GS-T]

I've had issues with my car for awhile now but I finally got it in a good running state. First I was having electrical problems, then my crank positioning sensor decided to go out and now this. I was at a car meet last night with a few of my friends. My car was un-tuned and I was talking with another DSM owner. He had his computer and his adapter (My adapter is bad and won't let me connect to my computer). So I plugged in his adapter and computer and DSMLink went right online. I have my tune saved to a flash drive and I opened it up on DSMLink and saved it to the ECU. I know the car IS tuned right now. I have the stock boost gauge set to read LTFT (Amount of fuel the car is receiving) and it's doing much better maintaining a good level and it get's better mileage now. However, for some reason, the car WILL NOT rev past 4500. It pulls incredibly hard (New header and O2 housing spool the turbo very fast now) until that 4500 RPM's but after that it's almost like a rev limiter or something. I watched the gauge that I have set to read LTFT when I throttle and it doesn't rise or fall, meaning I don't think that there is a fuel cut in the system. I've checked for boost leaks but I don't think that's the problem as well. At idle the car is at 19/20 vacuum, where I believe it needs to be.

Any ideas or thoughts? I'm completely stumped.

He must of messed around with your seatings on dsmlink you need to log into dsmlink and go on ecu rpm settings he most likely set your rev limitear for 4500

It's a possibility but I was pretty certain I had my limiter set to 7500. I'll double check it when I get my cable back from ECMtuning.
