I recently had my hondata installed/tuned at RPM. I bought a greddy manual boost controller from them as well so it could be tuned to 10psi. I was running a restricivie 2 1/4'' exhaust so it spooled a little slow. But ran great. So the other day i dropped the exhaust so it would just be an open 2 1/2'' DP. The boost went way up from not having any backpressure so i turned it down. Now it takes till freakin redline to reach 10psi. if i turn the controller up....it goes over 10psi at redline. I dont know whats wrong. This thing should be spoolin fast as ****.
BTW

99 civic si
DRAG Gen 3 turbo kit
MSD 6AL
RC 370cc injectors
