So I have a pretty big problem, nothing crippling bad, but still annoying. Anyways, I am driving home from work tonight and noticed that when i went full throttle the power was choppy and dropped on its face. It feels fine when I am going half throttle or a little bit more. There are no abnormal noises from the engine bay, but the exhaust got poppy when i went full throttle.
According to the boost guage it boosts up to 10 spiking at around 12, but I feel little to no power, and if I do it is bouncy.

So a little info on the engine, completely stock except for 3 inch turbo back exhaust, and professionaly tuned AFC neo by Jack at P1 (doubt that is the problem). Other then that nothing special. I am a little bit confused as to what could be wronge ( I am terable at diagnosing problems), please help


oops accidently put RB29 in the thread title , hell yeah I wish

 

So do you have an RB26? I'm not sure about the problem but I would start by checking all of your vacuum lines.
Good luck with it.

 

I have a RB20, I just accidently pressed 9 instead of 0

anyway, I am going to check the spark plugs, MAF and see if there are any vacuum leaks. I will see if I get any results.

 

yea definately sounds like it could be a boost leak, ignition, or fuel problem.
