You sure? 30 hp by porting the stock intake horn? How did you come up with that.... Did you dyno before and after? I did it before on my old LB7 and definitely did not notice a 30 hp gain... It made it sound a little louder but that's it...
The porting and polishing I did on the exhaust and intake side is what yielded 30hp, not just the intake horn. A friend of mine was nice enough to jump on dyno before and after installing the turbo; it also ran a 12.30 on the track. It woke it up pretty good and moves.
I'm not a tuner by any means; just from my reading it seems higher EGT's can be caused by more air, but again I'm not pro.
