if the car was tuned with some other programmer, your going to have to return it back to the stock config first before you tune with HPtuners.
Your vortech kit probably came with a diablo tuner, and the Hp software is giving the error because it's unable to validate some checksums from etc tables, etc...
Good luck.

Well that’s not very cool, well I guess If I’m going to use there program for fuel and air, I guess I can't reefer to it as my programmer considering I’m sure they did this on purpose So I will first do the trans tunes with hp tuners, then stack there tune onto mine, considering there programmer doesn't have any trans stuff to modify, and for some reason forced induction on the mustang with auto causes the trans to not shift right and stack 3rd to 4th gear, any ideas on a way for me to correct this. I can modify with hptuners then just use there programmer for fuel and air, I have a wide band and that part is great I don't even want to mess with it, If my car was a manual everything would be ok, but there is no tuners around here at all so I don't know what to do.
Send the file to support with any info you know about the pcm previously ie has it been tuned before, with what software or handheld, etc. along with your serial number and I'll see if its a file we can support.

I have looked everywhere Bill including the support page,for a place to upload my file I will attach it here, This vehicle has 3000 Miles, the only time I used hp tuners on the vehicle is when I changed for final gear ratio, and revs per mile, and disabled the feture needed to correct the speedo, other than that I installed My Diablo Prediator VR7140, Once I install the Prediator then I get the error, if I remove the diablo program, then I can do a read entire any time. In order for me to do a read entire I must first uninstall the diablo program.
This is the file I tried to open, that will not open after the install of the Diablo.
Yeah the checksum issue created by diablo is not able to be fixed with our software.

I assume they do this on purpose to protect there tune file, Kind of like a tuners lock, except instead of having a password, they change the way there application modifies different parts of parameters to cause a compatibility issue, or checksum error, but doesn't aversely affect the ecm, but instead make it so other tuner apps can not edit, so that way its proprietary.
we don't correct the throttle checksum if it is incorrect. it is there for a reason, that is as a protection in case of a PCM ROM error causing erratic (or worse wide open) throttle operation. Our software (and SCT's that i know of) calculate this checksum whenever any throttle related parameters are changed.
I count sheep in hex...
Well when I scan with hptuners, and the trottle is all the way to the floor, Hptuners reads 78 percent throttle instead of 100. Whats the cause for this.
its becuase of the way some manufacturers interpret the SAE PID for throttle. most seem to interpret it as the absolute voltage from 5V. GM used to interpret it as a percentage but they also have changed. eg. the LS2 and later engines all read 88% at WOT on the SAE PID.
