Hi, I went from 235/55-17 to 235/50-18. So my question is do I need to change this in my tune? And what are the values I'm needing?
Thanks
I think thats the same overall diameter. Best thing to do is go to the tirerack website and look-up the specs for the tire, you'll see "revs per mile". Then ...

So doe this predator tuner support turning off the O2 sensors? Or are they turned off in my 91 bama race tune?

Hi, I have 07 Mustang GT running C&L racer CAI with a 91 oct custom race tune and PYPES axle back. I recently moved to a town that only offers 87 and 89 octane. Posted here before and was told to modify global spark -5 degrees. Here recently I been getting the error code P0430. I plug in predator to ...

One last question. So when I do the modification, and then decide to go back to 91 or 93. Will the new modified tune be saved on the predator and I will have to add back to the global spark setting? Sorry new to this, just want to make sure I don't f anything up.

Thanks!

Plug in the tuner and then modify tune?
Thanks

Hello, I have a 91 custom race tune for the predator tuner U7145 on a 07 gt with c&l racer kit on it. Anyways, i moved to a tiny tiny little town out in the middle of nowhere with a gas station that only sales 87 and 89 octane. So I'm looking to see where I can have my tune modified to run the 87 or ...

Thanks tuningss for answering my questions, I will be contacting you soon. Question though, here in Kansas we only have 87,89 and 91 octane. I have really only ran 89 octane, is there a 89 tune? Big differnce between 89 and 91 tunes?
Thanks

Ok that answers my question about getting a custom tune. But is the c&l racer "canned tune" on 8r07 the best way to go or should I update the tuner to 9r07 and use the 95 mm generic tune? My other unaswered question was how come in other post people were giving a custom tune to download so how come ...

So I downgraded u7145 to 8r07 so I could get the c&l tune running on my car. It seems to work fine. I am new to this and this cai is my first mod. So was downgrading to 8r07 the right way to go to get the c&l racer tune? Also before downgrading I updated to 9r07 but was unsure what tune to use?? I ...

I just purchased a used c&l racer cai with the predator tuner U7145. Anyways, I installed the kit followed the prompts on the tuner and went with the 91 performance tune. Everything went somethly and went for a test run and the car was boging really bad and the check engine light came on. rechecked ...
