Question Throttle sensitivity

I have a 2006 mustang gt (not original owner) with a few mods such as a Bama race tune, K&N Cold air intake, and a BBK 62mm throttle body. I've noticed that I have still not gotten used to the throttle sensitive, would reversing to a street tune help? It currently has a race tune. and are there any precautions i should know about before reverting back to a street tune?

Definetly flash back to stock before reverting to the street tune! I reflashed my ECM, without returning it to stock and all sorts of codes were being thrown. When I flashed stock, then reflashed to street, race, whatever, no issues at all. The process takes a bit longer but well worth it.

Yes, the race tune has a very touch throttle response. I didn't like it so I never use it. I use the performance tune.

Go with either a street tune or performance tune. Street tune is pretty mild though. Performance tune is a happy median.

No issues.
Just make sure the octane in your tank is currently equivalent or higher that what's required for the street tune.

I never experienced any issues going directly from one custom tune (89) to another custom tune (93).

The car ran fine, no problems there, and it never threw a CEL But when I checked to make sure all of the monitors ran with no problem, I had a load of stored codes, such as "com link failure, software mismatch, throttle actuator control system-forced engine shutdown (engine never shut sown though) internal module software incompatibility." There were more, but I couldn't do a full screen capture there were so many. Oddly enough the car ran fine, but obviously something was VERY wrong, and this happened more than once before I got into the habit of doing it correctly. I've read about too many people blowing up their PCM/ECM while flashing. You need to be certain to follow the manufacturers recommendations! Be safe, not in a hurry!
