.5Hp seems about right to me, and that will only appear above 4,500 RPM

if boosted, might be able to hold higher boost(might be wrong?), but you will see more gains without CAT, nothing noticeable

u will be fine doing it urself im sure.

not only that, i cant tell you how much more respect you gain for cars by working on them urself. You might even come to really enjoy wrenching on ur car.
