Can't hold boost, did a boost leak test, check inside.

SO yeah, put on the new TB (thanks kevbo, works awesome), fixed my j-pipe bolt (turbo was stripped out).

DId a boost leak test about to 35psi. Small leak out of AFPR on the vacuum line fitting, i guess i need to use some teflon tape on the fitting maybe?
Only other place is the nipple on the top of the TB, i should probably have those welded up too. But these are really small leaks.

Anywho driving the car last night, car would spike to 33psi but settle to 22psi, i just want to hold boost steady and i can't.

Please help with any suggestions or ideas.

Thanks
Aaron

You want to hold 33psi to redline on a 16g?

Try using some colder gas. ;)

Exactly(agreed). Over upper 20's isn't happening.

Yeah our turbo's will always drop at the higher rpm. They aren't efficient enough and just run out of steam. Although if you went with an external wastegate you could hold the boost ALOT better to redline.

well 2gtsi on here was holding 29psi steady to redline. CB holds 30psi to redline.
Others spike mid to high 30s but still settle in the high 20s.

Anyone heard of the AFPR leaking how i described?
Know where i can get the TB welded?
