I've had the ford racing trackcal tune for almost 2years now and it has been a little unstable.great tune but the power seems to be when the tune Wants it to kick. Some days feels slow some seem more peppier. I'm having a issue past 2 weeks.when I down shift it cuts off my loopey idle feature and almost sounds like it's fixing to stall out when I come to a stop. I always check my a.f.r and it bounces from 12.8-14 pressing throttle and spikes to 20 when I let off well since I been having the weird decel problem my afr is staying in 14.0 no matter how hard I mash the gas but still goes to 20 on a decel then at one point last night it dropped to 10.9 when driving. Does anyone have any idea what the f*** is going on? Maybe bad gas? I'm checking on my warranty Monday I want the lethal ofr-h kit that comes with the lund n-gauge may jump on it sooner if the fr-trackcal is to blame.
I have the Track Key version. In cold weather the Lopey Idle comes and goes, because it is dependent on coolant temp. So if that's bothering you, have Lopey Idle turned off. When Lopey Idle is off, it seems pretty consistent. I can't speak to A/F ratio. I just drive it 😁
