At the time of the dyno I still had the stock convertor in my tranny so that was not a issue for the dyno outcome.

why are your running ngk t6 plugs?? you dont have FI, so those arent necessary. you need a hotter plug. just an idea. i would've expected more, but it is also an auto and untuned.

With that high of an a/f ratio your motor ain't gonna last long. 13.5-14 is way too much.

oh yeah, check your injector duty cycle. might be why its runnin rich.

Yup. A lot of mental ************ until we got an answer to that.

Yes, it is a big factor. The stock converter unlocked still loses 4% or more compared to a locked converter. Compared to an M6, you are down even more since an M6 is more effecient.

those numbers are very good for an unlocked auto. A tune will probably get you close to 400RWHP

ok, so an untuned, unlocked TC and TR6 plugs? The #'s are what you should get.
