Looking for some ideas for help with my tune. Car starts but stalls unless I hold the throttle and let it warm up. Any tips on where to start adjusting?

Combo is a 1990 Ford Mustang GT with a Microsquirt.

306 with Edelbrock RPM heads, 1.6 Rockers, Lunati 51014 Cam, Edelbrock RPM 2 Intake, Accufab 75mm TB, 60lb injectors, Vortech S trim with intercooler.

New to tuning and Microsquirt so opening to ideas to help out. Tune file is from some other local folks with semi similar combos.

Thanks!

What you want time off? :) Certainly interested in remote tuning help and class on proper use of the software and not break stuff. I suspect I may be approaching the magical range when stock blocks could decide to split...Visual in case that provides any inspiration.

Thanks again Steve for your time and patience this evening getting it to a good place. Starts and idles like a champ and have a much better understanding of Tunerstudio and the settings. Even better have a plan going forward to get the tune the rest of the way there. Highly recommend a session with Steve to get your car in a safe place.

I’d love to get some of the info to if you still have it

Just curious how you like that lunati cam? Just installed the same one in my combo with trickflow trackheat and brodix st 5.0 heads. So far it seems to work pretty well for me
