How much extra hp
Ok can't wrap my head around it. How much extra HP do you think I am getting at the flywheel with these mods BBK long tubes, K & N cold air intake Borla axle back exhaust and trifecta tune? From looking at other peoples Dynos I am thinking around 30 to 35.

Maybe but look at this way.
20 HP for headers, 15 for an intake, 2 HP from the axleback (being optimistic, axlebacks usually dont give anything on this car), and finally 13 for trifecta. If you add them up, its 50 at best. But since Hp doesn't add up like that, 40-45 is probably more realistic. And even at that, that's being optimistic |

With BBK LT's, CAI and a tune I went from 373 stock to 430rwhp post tune.
Just the headers and intake was up to 412. Sent from my iPhone using Tapatalk

yhea. I would think so on "average" from many many dyno numbers I been seeing and collecting. It could be more and it could be a little less but I would say 30 on average with LT header/intake and trifecta tune off peak. This motor doesn't peak well.

I agree with bmorecam that looking at peak gains is usually not the best way to determine gains.
That said, I feel you should be seeing at least 25 HP gain at peak at the wheels, with 30 to 40 or so around the mid to mid-upper rpms. I guess you at somewhere near 340 crank horsepower.

I guess I am a little confused. I thought trifecta tune was suppose to give an extra 25 stock. So if that is the case he is only getting 5-10 between his headers, intake and exhaust? Either I am missing something or something is fishy.

He started with 312 HP. I'd say he is now around 335 to 340, so theres your gains.
