That is all programmed into the powertrain control module. It programmed based on the speed rating of the OEM tires. the V6 Mustangs come with T-rated tires, hence the 115mph cap. the GT has higher rated tires and a corresponding highr speed limitsotes said:ive been driving my stang since mid-december. the gov. is set to 115mph, but thats right after i hit the 5th gear, and im only at 3000-3500 rpms, theres way more power to spare. anyone know how to adjust, perhaps know how i could take it off?

its easy to work out, just find out what the mph per 1000rpm is in top and times that by the red line revs, e.g.echo7 said:198, theres no way a c6 could do it, i wouldnt even think a gt could hit 198, to much wind resistants, but i think your math may be off some, sounds kinda high...
NJstangpilot said:C-daddy,
Do many performance shops have these calibrator devices and can/will they "flash" a car with your desired parameters so that you don't have to spend $300+ for the whole unit? I would like to have the throttle delay and rev limiter functions removed without having to buy a calibrator unit. $40 to $50 seems reasonable for the time/effort it would take someone to do this. Is this a common "speed-shop" service for cars?

The final result is only slightly different however, showing 6000 rpm in 5th gear to be 194 mph with the stock V6 tire size. Please note that this is a theoretical max speed based on engine RPM, gear ratio and tire size only. I find it highly unlikely that the V6 possesses the power to actually reach redline in 5th gear.
What were the RPMs at when you were crusing at 125?
