I've got some tuning questions.. kinda new-ish to the 12v motors. Had a 318is and then did an m50 swap on a different car, but I wanted to stick with the m20 on the current car.
I have low mileage seta bottom end with a rebuilt i head (stock rebuild, polished cam) held together with metric blue studs and Cometic MLS gasket (the motor has seen boost twice in the 10k miles it's been running).
I have rebuilt 19# injectors (Mustang units) and am running the proper SSSquid chip for this setup, and the stock m20 AFM adjusted a little bit - the car starts hard most of the time - especially when its hot, doesn't like to hold idle a whole lot, and I'm getting about 16mpg. It pulls great when it winds up a bit, but I really feel like the bottom end is dead and it revs slow.
I'm thinking that 19# injectors is simply too much fuel, should I back down to 17#? Go back to the stockers?
Or should I try an m30 AFM and chip - or do an MAF swap?
Performance isn't a huge concern, I just really want to get the car to run perfect and get the mpg it's supposed to.
