HELP!!HELP!!HELP!!

i programmed the 91 octane and accidentally hit factory hp tune. then i unplugged it and now it wont start. and when it does the gas doesnt work. i programmed it back to 87 octane and restored original back up and it still wont start and the gas wont work. how do i fix it?

Rear wheel horsepower can be measured on a dyno. Flywheel horsepower can only be measured by pulling the engine out of the car completely and testing it on the bench. There is no general RWHP = FWHP * 0.86 equation to apply to your question. With every car the loss due to drivetrain is going to be different, because every car is different. All that we can tell you is what a car very similar to yours had at the rear wheel before and after it was tuned.

sounds like the driver for the usb to serial cable is not working.

I wasn't sure how to go about submitting for a custom tune, so I thought I would try this... sorry if it's not the way to do it.
I have a 2007 Mustang GT 4.6L 3V. I have the Predator Tuner (U7145). The bolt on power adders I have are:
BBK Twin 62mm Throttle Body
K&N CAI
SR Underdrive Pulleys
Flowmaster Exhaust (Not sure which series, it was on when I bought the car - used).
I use only Premium fuel, the highest that particular gas station has (91, 92...). I currently have the 93 Octane/K&N CAI tune loaded in the car. Any suggestions? Incidentally, after installing the BBK TB, I must not have gotten it set perfectly, because at idle, the RPM's bounce about 50-100RPM. Can that be fixed through a program, or do I need to re-set the TB?
Looking forward to the response.
Thank you!

Want to put new tune on it and need help. Right now has original tune in it. Tried Diablo tune on there and it runs worse. Please help been going crazy trying to have someone help me but no luck. Should of came here long tome ago. I haven't done nothing other than try 2 tunes on it and original seems to run better. I want to put my Edelbrock Cold Air intake on and re tube so it runs to its potential. Please help I see you closed today and will call Monday if I have to but hoping I can get this taking care of. Speedometer not right tire sizes are Mickey Thompsons rears are 30x12.00x18lt fronts are 28x10.00x18lt. Im want to get this done just want the right tune to down load.
