Do I took my 2000 m6 WS6 to a local dyno event to get a baseline. Car has pacesetter Lt
and no cats and a true dual exhaust, slp lid with k&n filter, I deleted AIR, EGR and AC
from the car.....best run was 290whp and 302wtq, fo these sound low? Car has 109k and a new clutch if that makes a difference, no tuneing done other than having the codes erased with hp tuners

 

 

I thought these car's put 300 down stock, I was hoping for 320ish

 

thats really low you should be somewhere around 330 untuned. either the dyno is off or something is holding your car back.

 

Does the power curve look normal, btw this is on a dynojet

 

could just be a stingy dyno, looks fairly normal to me


EDIT: missed it is untuned...there's your problem

 

imo adding headers leans out the tune so your factory 14.5:1 is probably closer to 15:1 (again my opinion) after a proper tune to 13:1 you should pickup atleast 15 rwhp maybe more. stock dynos A4 i've seen as low as 270 and as high as 305, for a stick 300 to 315. just my one cent.
