hey all you guys running the power fc ... how will the car run with out tunning on the stock apexi base maps????? the car has all bolts on catless 3" exhaust and ported wastegate and motor and full fuel set up.....please let me know ....

 

It will run just fine...just don't boost more than a couple psi. You will need to change the injectors to the proper setting though. If you have 1600cc injectors, you need a Datalogit to adjust that high.

 

how much is a few psi??14-15?

 

Uhm...stock is 10lbs. You have all those bolt ons and the PFC is an afterthought? Don't boost hard or you will be saying good bye to your motor.

 

Rynberg adviced you a couple of psi boost only. He is correct. Don't run any high boost without some kind of tuning. At the least, get a wideband Air/Fuel gauge to monitor your mixture.

Base map may run you way lean at the high boost/RPM range and blow your engine in a short order. I got a "richened up" basemap with my PFC and still ran lean with less mods than you have.

 

15psi, lol KABOOM! 11-12 is safe with those mods.. i personally wouldnt go any higher

yeah ... so i guess tunning is a super must .. i do got a air/fuel gauge.... thanks for the tread mahjik... so is there anywere in northern cali that is capable of tunning my seven... and hopefully not blow it up???

 

I've got all the bolt ons, full exhaust, no cat, intake, IC, and stock fuel, and mine runs fine around 10-12 psi with the stock maps, I haven't pushed it much past 12, due to stock fuel.

I've had it tested with two different O2's and the max I saw was about 11.1 afr.
I did turn the PIM volt up about 2-3% up top 7000-8000 to flatten the curve out though.
