It's all been a lie....

??? I'm pretty confused whats the lie here?

I think that "bolt ons won't give you any measurable gains".

so then explain my power bump

I have never heard the myth that bolts on don't give a power bump for our car. if you get headers with a tune, it will definitely give you a power bump. same with some intakes as well. however, don't expect to get over 200whp with bolt ons unless you go e85

That's an impressive gain.

So, is your car's header stock .. ??

Stock tune ..right ..... ??

Running on mostly gasoline .. ??

Are you running lean? Check your AFR.

Stock tune is very rich

Intakes can effect AFR which is why he asked Im pretty sure. Intake runs lean adding HP but not as safe.

IDK if the Perrin does but thats a big power bump on stock tune. Did you do more then 3 runs and was the 165 you car or just another car on the same dyno

and would be interested to see the actual plot to see the whole powerband and whats gained under the curve vs peak numbers

Ace header has hit 200 whp in some cases
