Pretty General problem...

I already have a stock MAF on its way, so I am going to throw it back on... the problem is I won't really know the difference until I can get back to the track though.
A copy of my Dyno sheet before the ported MAF and ported TB.. the car was making good power, tons of it under the curve... so with that power there I know my trap would have been a bit higher then 106.. I was thinking around 109-110. I'm afraid though that a ported MAF can't **** up my HP enough to kill 4-5 HP in the quarter mile though...
The dyno I went to did not have wideband.. so I couldn't tell you what my AF ratio was.

well if you are using that much oil and its not on the ground, guess where its going! right through your throttle body most likely. i hear that can cause a fair amount of knock retard. i think we are getting warmer here! run a heavier weight 10w30 or (page him to check or do a search) patman is running 0w40(?) and is having luck with that. get a catch can! i need one too. good luck

I am pretty sure the computer is just retarding timing instead of it being an actual mechanical problem, stupid Ls1 senstive PCM's.
Tuning is probaly my only hope.
