speed/rpm restrictor chip?

so i got my 97 gst turbo a few days ago from the auction, i just got it fixed, and i found out when i tried to redline at 7k rpm, a chip or something restricts it to 3k rpm...and in fifth, since its restriceted to 3k, i could only do 60!!!! aahhh, im mad.   so how do i take it off, do i just go to a mechanic or could i just do it myself, if i can plz tell me how.

whatttt?? ive never heard of that before.. take a video of it if you can

Something is f'd up. Whats it doing when you hit that rpms. Cuz that definetly isnt right. These cars can do 125 if you let em

lol ouch man that sucks arent they supposed to cut out at 130 the gst's? ya something isnt right.

I say air leak

does it only do that when your flooring it? or does it do it all the time?

Could be ECU

i have yet to replace the thermostat and the oil, cuz they are both bad, and  i took a look at what my boost gauge was connected to, and the clear tubing that i guess mesured the lbs of boost, is cut! and it sounds like my boost gauge is leaking, so i need a new one of those.

nvm, i drove it just now and i got it over 5k rpm, idk y it was doing that yesterday.
