i have a mk 4 astra sri 2.0. i realy need more throttle responce because this is where i loose out, outher cars seem to pull away from me when we both floor it, and i can only come back in mid-range, the mid-range in my car is good for what it is, but i want moore.
i am thinking of a cat ack system from power flow and a induction kit! but will this make a noticable gain, it did in me many nova sr's, but im not shure about the gains with the c20xev???
PLEASE help if u know any info???????
