They sent the U7140 not the CNL7140 I hope it is not to hard to change it.
Thanks again
No need to send it back
I'm running the U7140 on an 05 with no problems.
Call diablosport with the Cal_id of your car and they'll email you the proper file.
The advantage of the U7140 over the CL7140 is that you can use it without the C&L intake.
If you only want to change gear ratios,tire diameters, fan settings while running the stock tune you can do it.
That's how I did my back to back testing.
Keep in mind that there are 2 updates for the U7140 Predator.
First there is the firmware update which must be done when the programmer is in its stock form.
In other words if you had a tune in your car you would need to reinstall the stock tune and reset the Predator.
This firmware update is the R28 update.(crom file)
Second is the .frg file which must match the Cal_id of your car.
It's the frg file you need to get from Diablosport.
