Recently coming from a 3.4/headers/rockers/intake setup. I just installed my Phenolic Full size IC and dropped to a 3.0 pulley with no KR @ 10.5 afr and 17* timing.
Now my trims are all messed up. + 7 to 13 at idle. In certain spots at cruise I will hit high teens in both trims. As on my old setup I was +/- 5.
For wot in this setup or old they are locked at 0.
Now the reason I suspect it is not a vacuum leak is because when I remove my oil cap my ltft spikes to +16 (from +10-13) When I put the cap back on they drop back down to around 10.
Now does going to a 3.0 from a 3.4 really draw that much air in to make that much of a difference other than wot?
As I used RTV where it was needed to seal the supercharger and LIM to mounting surfaces.
But I could be wrong. Maybe I have a leak somewhere besides the mating surfaces?
