the throttle position sensor is a weird code to have. You have probably gone to speed density and disconnected the Maf and Map sensors. Those would cause all the codes besides P0121. I would check the connector on your throttle body and make sure you have it connected.
I would think this question you should be asking your tuner... If you put a log up that would be helpful to see with TPS, knock, AFR, rpm, spark, Inj duty cycle at the minimum.

Have you cleared the codes out? How long do they take to come back? Also whats the total history on the car? How long does the CEL have to be on for the bulb to actually burn out?

New cam sensor did NOT clear up my issue, but Im going to keep it. yes I cleared the codes, they come back almost immediately after I do a WOT pull. The car is a 2003 I think the bulb just burned out. I was not driving around with the SES light on. Other suggestions? If I cant come up with anything im just gonna take it to the local import mechanic.

Are you running aem ems series 1? I was having a similar problem, backfiring during boost, not pulling during boost when it's backfiring. It was definitely a fuel issue that I was happening to me, but it was due to the EPROM failing on my aem. I finally just figured this out when I went to my tuner and my secondary injectors weren't turning on. Then the car would no longer commincate with the aem. And it wasn't firing my fuel pumps, injectors and no spark. I would look into an issue with the aem, once I did, it really showed itsself and the aem took a dump

Did you ever check your cam timing, or are you just ASSuming that its fine?
