'95 talon tsi. swapped evo 3 motor with AEM for management. Turbo: SC34 mitsu, hks 272 cams, hks evc, shepherd stage 4 trani.
My problem is that as soon as the turbo reaches full boost at around 5500 rpm, the engine virtually wont climb any higher. rpms are forced to stay the same, boost stays exactly the same, speed stays exactly the same. It will go clear through first all the way to redline, but second, third, etc. do the above. I plugged in my laptop and ran 3 maps, all of which show the tuning to be flawless. The engine temps are normal, there is a slight tick in the engine bay at around 3k if you rev up then allow rpms to drop quickly you catch the clicking noise. I've written it off as lifters until this situation.
Before tuning the engine ran all the way to redline in all gears. If there is any other info I can provide to diagnose, please let me know. otherwise, whats going on?
