the engines been feeling sluggish, misfires at idle and idles at around 1500 rpms, when boost kicks in the engine light comes on, and theres no power

Code 11 is interrupted power to the ECU. Check that the grounds at the rear bottom of the intake manifold are connected and in good shape.

Yep I just had that code 3 days ago... It was a bad ground connection.

I'd check all the grounds and loosen and retighten them.

Okay I checked the grounds the ecu getting power at all times, the misfire is weird, on cold starts It idles fine with no hiccups, but when it gets warm to normal temp it misses badly that I can feel it through the whole car and out the exhaust. this all didn't happen until I changed the spark plugs from BCPR6EGP to BCPR6ES I had no issues with the BCPR6EGP plugs, and I changed them because i though i was loosing power and because they were the plugs I use to first start the rebuild engine about 2000 miles ago, I had satisfying power for a restricted exhaust, but now all disappeared and misfire when I switched to these BCPR6ES NGK R. Currently stock engine, stock boost, 2.5 intercooling, air intake, 3" exhaust. all spark plugs were pre-gapped 32
any info this please, new to turbos

Gap the plugs to like 28. Also always double check the gap.

The ground should have 0v.

Okay now I have a code 51, and 52 because my knock sensor broke, but the other one has something to do with the tps

 

[mk3-4-me]

Try recalibrating your tps... I had to a couple times... Its real easy, just gotta have a voltmeter.

 

[STREET90]

Okay I will go back to the spark plugs I started with, and recalibrat the tps, also, will a knock cause the engine to run sluggish if broken? I have a auto ecu but I'm manual

Am I doing this right? following the trsm
