Limp Mode.. check engines for everyone!
Oh lord.. where to begin. Driving down the road today, have the gas a whack probably 80% throttle and the car commits suicide lol starts running like crap and display reads reduced engine power mode...
check engine codes...
B2265
C1278
P1515, 1516
Where to start? Car drives fine at part throttle and seems to not like WOT or close to it, as it just goes into this mode again. Car is heavily modified and tuned, never had this issue with this car in my 6 years of ownership.
I appreciate all suggestions and information. Thanks!

check the throttle body sensors and connectors, I had the same issue recently and somehow a pin to my tps sensor was opened up and making bad contact... that's where I would start

but the connector is still oem right?... that pic is on the engine harness connector not the actual tps sensor... if you have any extensions or conversion harnesses for the throttle body check those as well
