Well I have a tail wastegate and the hose should be run to the port on the side, when they put it back together they put it on the top port which prevents the wastegate from opening. The mechanic was driving it when the headlifted and caused the car to go into limp mode with a 2500rpm rev limit. He said it was a hose he popped when it happened, it never occurred to me to check the wastegate

Finally got error codes for the CEL. Codes were P2135, P0605, P0304. The P0304 looks like it came up because of the excess fuel that was being poured in because the car did not want to start at first and i was getting smoke out the exhaust. I'm going to the shop to pickup a throttle body and pedal sensor to try them out.

I'll try a manuel reset before switching a throttle body. My mechanic gave me a spare throttle body and pedal to try out. The reset shouldn't mess with the Osiris tune?

P0605 is concerning. If I were you I would redo the primary engine ground before anything else. There are two cables on the front timing covers joining to one that connects to the frame rail on the passenger side. Disconnect battery (important!), remove all three ground points, clean/sand down/grease and reinstall tightly. This will effectively reset the ECU as well. See what codes pop up after that.

Problem seems to be solved
P2135- Bad throttle body. swapped out for another throttle body and car instantly was getting throttle. Drove for about 30 minutes with a mix of cruising and getting on it and no issues.
P0605- seemed to be a lose connection on the battery which i just loosened, pulled off, and then reconnected
P0300 0r P0304- Still getting a code for it but no CEL at all. Car seems to be running fine but a Little bumpy at times. i might have a fouled spark plug. my car does run a little rich at times so it could be tune related

Interesting!!! When you would rev did it feel like it was bouncing off the rev limiter at 1500 rpm or did it just accelerate to 1500 and not give any more throttle? In my case i would floor it and it would slowly climb to about 1400-1500rpm but no bouncing off rev limiter effect.
