So when i full throttle it the first time it will max the boost gauge out and blow off fine the second time is a differnt story. Itll be full throttle but wont go higher than 3k -3500. People say look for boost leak but me and my dad checked and found nothing. ( it idles fine). I have an aftermarket hks bov that non recirculating so i think that may be the prob but if someone knows lmk thanks

what exactly is the issue? is it the downpipe? or not revving past 3k-3.5k? post title makes no sense to what you wrote.
Also what engine? Be detailed.

I would also like a little more detail on your problem you are having.

Are you sure its not hitting fuel cut once you are boosting (engine lights comes on for a few seconds and it cuts fuel to drop RPM's very shortly)?

I am also running a HKS non recirculating bov and I have no problems on the OEM ecu but mine is only set up like this temporary as you need to have a recirculated bov for the OEM ecu.

Its a 7mgte with a 3 inch non circulating dp and catted exhaust. Stock everything except for that and hks bov. Engine light does come on when i hit boost and stays there. It had the CEL even without the downpipe.

check again for boost leaks, i use a can of brake/carb cleaner around the pipes while the engine is running. dont drench of course just sparingly. you'll hear it rev up if there is a leak.

now what are the codes.

Ya it was a rip on the intercooler coupling near the headlights. The rip was underneath and i guess when i took it off for the downpipe install it made it worse im assuming. The coupler slipped off cause the rip was near the edge.
