    weird boost? laggy

    So my cars on 10 pound max but it only gets there at max rpm like 6500rpm, i thought full boost should be on at like 3500 and also my car is very slow and unresponsive at down low rpm but only gets going at high rpm. is this normal or is there something not right?

    Boost Leak?

    FS: S15 dump valve with internal modification

    I have my original dump valve here. It has an internal modification - the small hole which causes boost leaks at higher boost levels has been blocked off. This all means you can run more boost on the stick valve/pipe work. £20 delivered
