Tuning idle for 1000cc

[Whitltng]

Having some issues with idle and driveability.

My set up
2018 mustang a10. Vortech v3jt 3.6 pulley. delete cats ,3inch exhaust, ported mani, vmp bap ,fic1000

Car seems to die when returning to idle.
I know what some might say . Change you tuner , go with someone with more knowledge on the car. He is very well known in the gm and dodge world and has tuned alot of ford but not alot of the 18 19 mustangs..
Looking for a technical answer not bashing him as a tuner .

My issues are the car dies when returning to idle seems to have why to much fuel with both injectors running .. he fixed the issue with turning the port injectors off but the computer still wants to command the injectors to fire..

My question . Is turning off the port injectors when running a large 1000cc injector the fix for normal driving and idle.

It is not. you answered your own question. Find a new tuner that is a late model mustang specialist. Tuners across the country are getting more and more diverse to which platforms they tune because they've become so advanced/complex.

find a new tuner, being able to tune other platforms well does not mean they can tune Fords. Tuning Fords is nothing like tuning GM or Mopars, completely different platform, they are torque based

You may get a more technical answer or guidance on HP tuners forum, lots of great info over there. Tuning newer vehicles, especially the Ford Tricore is becoming more and more advanced and it really is best to use a tuner that has spent the time and money to research and dial these cars in.

Majority of guys don't self tune here, go on the HPTuners forums. You will get much better answers.
