A while back i posted a question relating to boost drop-off.I just wanted to post an update because there were a few people who had the same problem that has the same set-up as me.
The set-up was b16a with a garrett t-3 (.42/.48).boost would drop-off around 5,500rpm.
I solved the problem by buying a larger turbo.IMO the drop-off was due to the fact that the turbo was to small and couldn't flow enough for this engine.
I even hooked my tial wg up with the old turbo and boost still droped off.Although not as bad it still droped off.
So just giving an update to those who experienced the same problem...
btw the new turbo is a t3t4oe boosting a solid 7psi..
