Howdy all! I seem to be having a bit of an issue with my 2015 ebm. I always suspected my car was down on power. Recently I picked up a Cobb tuner and confirmed my low side fuel pressure sensor was reading a big fat 0 at all times. Figured I’d replace that and get some power back, simple, right? No so much. After replacement I noticed my stft and ltft are both wayyyyyy outta whack.
I’m still getting stft adjustments of +/-28% and ltft adjustments of +/-18%. I’m on my stock map and still seeing that much adjustment. My mods are a drop in filter and CVFab catted downpipe. Ugh, and I’m still getting down into the 10’s on the AFR gauge. I also just threw in a set of the NGK 6510’s gapped at .026. So fresh plugs, known good top tier fuel (91 because Nevada), even tossed in a few gallons of 100 octane unleaded race fuel and still no difference.
Where do I go from here? Cause I’m ready to trade this car in. With the mods, it still feels slower than my stock 2013 Mazdaspeed3. Even with a 1.8 60’ my best 0-60 was 5.7s, and 1/4 mile of 14.7@92. Woof. My previous 2014 Caddy ATS went 14.20@97 stock. I thought I was gonna go faster with the Mustang...
