Default Mods - Dyno results

I have a 07 VERT MN6, with ~800miles.

Mods:
LG Pro LT headers with high flow cats
Corsa Sports

Dyno results of 366 rwhp and 368.5 rwtq after a tune. I don't have before sheet but was advised by tuner that hp increase was 32 from stock.

Is this a bit low or in expected range? Will it go up some after I put more miles on? Just curious, I love current performance and sound so HP numbers are not too important to me.

Just for sake of 'mod completeness', I may throw on a CAI and dyno again in a few months. Will a CAI add any significant amount of noise? Don't want much more, I am at a good level right now. The LGs and corsa sports RIP!

-Dave

My 900 mile old 07 coupe M6 (BONE STOCK) with only a custom tune dynoed at almost those SAME exact numbers you got on a dyno jet. My numbers were SAE corrected and I am at sea level(no elevation). Yours seem low for sure if you have headers. My tuner said I should be pushing 400 with header/catback and a retune. Better get a second opinion.

Check to see if you have the 799 heads. Your numbers seem about 10 hp low.

the 799 are the hot heads over 243 now since it is semi CNC.

cai will not increase your exhaust noise.

Maybe he was wondering about more intake noise, and I did experience that with my cobra when I installed a CAI over the stock air box. You could hear the sucking and more engine noise, but it was welcomed.

32 RWHP is a good gain from your mods. The car was a little low, stock,it seems for a M6. Usually the A6 is the bottom feeder when dyno'd stock. Mine was 337 bone stock. You may dyno a lttle higher after you put more miles on the car. For some reason, a 5 or so RWHP increase is often seen after a few thousand miles.

It sounds like a solid gain. All dyno's are different. Yet another dyno and see what it pulls
