I'm going to replace my gsi with a vxr unit and a front monted inter cooler . Then a remap . I don't really want to spend to much on it but want good gains for the money. What bhp do you think I'm looking at from this upgrade ? Also is there anything else cheap ish which can go with this to increase it ?
Thanks in advance
