SN95 On3 kit No Tuning
Hey guys, im considering buying an SN95 5.0 to build a turbo street car out of, using the on3 kit.
My question revolves around tuning one. I would want around 400-450whp (through a T5), using a stock 5.0 with gt40 heads and intake, maybe an OTS cam.
Ive searched for how people are tuning these with the stock PCM and coming up short. I know megasquirt or another standalone would be best, but a 94 or 95 would still need to pass a sniffer around here for a few more years. This is why Id like to use the stock PCM and keep all emissions equipment functional if possible. Then megasquirt it after its 25 yrs old.
I spoke with a foxbody owner at the track a week ago, and he has an on3 kit with a stock bottom end, 42lb injectors and a calibrated maf running 12 lbs. He said no tuning involved.
In my search I found a handful of people saying the were running the bigger inj, calibrated maf, and locked or lowered timing, but cant find any mention of additional tuning.
Most of the stuff I find people are saying to get it dynotuned.
So my question is, if I have the calibrated maf, bigger injectors, and adjusted the timing accordingly, would additional tuning be required? What is it they can actually change with the stock PCM? What components are needed to tune the stock PCM?
I know in the miata world, for a long time people were using RRFPRs and ignition boxes (band aids as they call them), now with the popularity of MS they are looked down upon, but they are still a lot of people running around with band aids and without tuning. This is what Id be wanting if I could do it relatively safely.
Im new to the mustang world, I have always had GMs myself, and about the only in depth ford experience I have is building a buddies foxbody. Its a GT40 top end, with an Fcam and bolt ons. He had it "dynotuned" and it made like 280whp. He later told me the tuner didnt do anything but set the timing and troubleshoot a drivability problem he was having, because you cant do much with the stock PCM. So I have no idea, and am looking for some guidance.
