Default how to turn up boost on comptech already on 10psi

i own a comptech supercharger novi 1000 on my ap2 with a 3 inch pulley who supposed to made 11 psi of boost, but because of my front mount intercooler i loss 1 or 2 psi and cut off set to 8300 rpm...my questions is how to make more boost like 12-14...i have a kpro 750cc rc injectors,wather meth injection,walbro 255.
whats the solution for more boost
thanks

1. Bigger, better flowing exhaust
2. Head work
3. Smaller Pulley

Terror is incorrect unfortunately.

A better flowing exhaust and head work are going to increase the efficiency of the system resulting in more power but ultimately at lower boost levels.

The only way to increase boost with your SC is to move to an even smaller pulley. Since you redlining at 8300 you could probably step down to the 2.8inch pulley.

You could also ditch the FMIC and run more water/meth to regain the boost you lost by adding all that extra space in the piping/core.

How big is the IC piping? Try to get a 2 1/4 piping or a more efficient smaller ic to regain boost level. I know a friend had comptech with 3" IC piping and boost dropped 2psi he changed the piping and gained 1 1/2 psi and better throttle response.

Its odd cause I remember someone just running the 3" with comptech and he pulled 13psi, but I guess it can change from everyones setups

why are you only revving to 8300 in an ap1? rev to 9k and u will see more boost

then get a smaller sc pulley, but then worry about belt slip. if you increase engine efficiency, you ussually gain power, but lose boost, but that doesnt mean you lost power.

i used to have the comptech 1000 blower. i dont know why your losing boost,

get a 70mm exhaust,
2.8 inch pulley since your redlining at 8300rpms
Ricks' headers or anything other then stock.
Get a better intercooler or get the After cooler that can come with the kit
