Ok to start it off ive been noticing my car low on power up until 6.5K rpm seems like its sluggish in lower rpms..

HAving installed the BHR coils the car immediately ran very lean idling around 14.9-15.7 AFR'sEven sometimes as high as 16's

i removed the bhr ignition coils and the car ran a little better less noticeable.. but the power loss was still there. its idling at 14.9-15.3 afr's wit stock ingnition.
thinking it was maybe MM tune i switched back to stock tune and was still the same minor improvement.. I thenflashed to MM base map and the car ran muuuch better but still bogs at idle making my oil pressre gauge beep.. rpms go from 850-723 rpms around that area.. some white smoke also tends to come out of the exhaust pipe.. Im wondering if this sould be a bad motor seal??? or maybe my fuel pump starting to go bad??????

AFr's are around 14.5-15 all the way until 5.5-6K rpms then they drop to like 13 at 6.5K rpm then 11.2-11.9 to redline..
just trying to see what you guys opinion on this could be.

only thing i can think of is that your o2 sensor is stuffed ....

Hmm also that did come to mind but i wasnt sure... Also want to point out that when i when back to stock tune the car idled and then kept turning off..

Not sure gonna have the check the o2 sensor.. i was gonna pull the spark plugs and see how they looked..

thanks brettus

but my question is why would it be much less noticeable with the stock ignitoon installed?
