Before and after (MAP short-runner exhaust manifold & MAP Turbosmart WGA):
There is a noticable increase in the mid-range, that's where I'm really feeling it. Plus, the turbo seems much more responsive with this new WGA which makes sense since the WG was able to be properly tensioned, I wasn't able to run any pre-tension with the original 25psi WGA. Although spool does appear a touch slower, torque picks up a little bit quicker.
Knock CEL is setup at 3 counts (slow) and 5 counts (fast), but I've yet to see a single flash even with two pulls to 140+ so far
