I'm tuning a customer's Procharged 2019 Mustang GT with an A10 transmission. Cold idle is a bit rough, but once warmed up, idles smooth. Then, for drivability, the throttle is really lazy. I have played a bit with driver demand settings, etc, but not much improvement. With the IMRC's deleted, I expected a little loss of bottom end torque, but this seems excessive. There is a lack of timing adv aroud 2,000-3,000rpm at about 50% load, but don't know if that is the culprit. If someone could look my tune file and log over and see if they notice anything like ETC torque requested or something like that, it would be great to have some help. I'm tuning this for a customer, which has been very patient. It is our first test on a boosted car, and it hasn't been a real great experience so far. We did WOT tuning on a dynojet in hot, muggy Florida, and it put down around 552hp/443tq, so power wasn't mind blowing. 2019 GT Procharged A10.hpt drive1111.hpl
