I saw a thread somewhat like this but I wanted to add that if I am banging through gears or let off when I’m in higher rpms and it doesn’t drop below 3500 before I get back on throttle I won’t have boost. So I’ve just been driving rolling into boost and then usually loose it around 6k. 2nd and 1st pull all the way through though. Any idea what’s wrong. And I recently did change almost all my solenoids.

 

Most likely a turbo control actuator problem. TONS of threads on troubleshooting that, do some digging and troubleshooting.

I have a jdm b16 n just completed the process of boosting it. Got it road tuned yesterday and my tuner disclosed to me I was losing pressure at high rpm. Im running off the waste entryway spring and its a 10.2 lb spring. The most noteworthy the lift goes is 8.8psi and than gradually drops down to the 7's when at high rpm. My tuner said this is a direct result of my exhaust how its so little, its a greddy sp2 60mm. Is that valid or is there something different wrong?

Wrong forun dexyah. Try the honda forums. 60mm is ******* tiny though, 75mm is the smallest I'd go
