I just got my Power FC installed and am looking for a good map that's close to my mostly stock '93 touring setup, or even some tuning tips. The only mods I'm running are a Greddy aftermarket intercooler and intake, big aluminum radiator with full-time fan mod and no cat at all (for now, anyway).

The car seems to be running OK, and my peak knock reading was 41, but it feels a little boggy under acceleration and I fear it's running lean at times. When I bought the car, it had an HKS PFC with Fuel Cut Defencer and was boosting close to 1 bar at max, which seems the same with the Apex PFC installed. I'm just not too familiar with that unit and what the previous owner might have done. Should I just buy a wideband O2 meter? Will the Datalogit alone allow me to tune it sufficiently? Can anyone recommend a good tuner in the Chicago area?

Any help would be greatly appreciated. Thanks.

Jon,
My suggestion since you are in Chicago would be to call either Sean or Steve at A-Spec Tuning. Those guys can set you straight on what you want/need to do. They've done most of my work and I couldn't be happier.

yeah, i've heard good things about them. i wanted to try to do some of it myself if i could get properly equipped, but maybe I'll just give 'em a call. thanks, nic.
