That is better but not enough??

Gained some more horses today but need more have a big prob with
lag have 40 more horses but the lag has also increased ten fold.

Previously put a bailey dump valve on (BOV) this reduced lag really well but
car wouldnt idle (STALL ON QUICK CLUTCH RELEASE) and felt brunty but ruff.

Well have removed standard return valve and replaced with
a forged return but lag is a real pain in the buttttt.

have you got a hard pipe kit mate? what kinda intake do you have on it from the filter to the maf? This reduced lag a fair bit.

No i dont have a hard pipe kit and sorry didnt understand question
as the apexi induction(filter) is bolted straight onto the maf.
