I have just thrown 35/12.5 tires on my truck and now it tosses a code when i am cruising down the road at 70 miles an hour, and then the auto gives a bit of studder and all is fine. When I had 295's on the truck I would toss the fuel code when I was loaded down with camper - 13000 lbs - and pulling hills or walking on it hard for a long time. I havent put the reader on it to find if its the same code or not but I am assuming so. Anyone else have this trouble, does the truck really have trouble pulling itself with these tires????

Any Input????????

 

PO148? DR. Performance is horrible about this code throws it even when pressures are at a acceptable level. They don't have a solution for it either the only thing they could come up with on my old one was for me too send it in and they would reflash it so that I could flip the switch to the off setting and after 30 minutes of it being off it would clear itself. I sent it back for a refund havent looked back since.

 

What is another better option????? I dont really notice the predator under normal driving, supposed to be like 110 at back tires, im having a hard time with that number, buddy an I went to the black hills this summer with the same trucks and campers and I couldnt really pull away from him in the hills and mileage between the two was very close to the same. What did you go to and is it untracable for warranty purposes???????

 

The DR. P box is mainly a big end box you really dont notice it until 70+mph imo. I have since went to the Quad X2 Race and love it lots of different from tunes for more low end to more big end to more smoke to mpg tunes and it has 5 levels adjustable on the fly with a built in rail pressure, boost, and ect guage.

 

thanks for the info. I think if I pull the Dr. P off then I think a smarty may be in the future............ still unsure........... so many options

 

How long have you had it they have a warranty and money back guarantee, give them a call you can easily buy a new x2 for the price of the dr. p.

 

Dr. Performance from my experience has been pretty good. I have the predator box but the standard programming made my rail pressure way too high, sent it to them and they reflashed it no charge and mailed it for free. Now its running right around 25,600 psi on performance setting with additional boost fooling stacked on a BD. Have not been on dyno yet but feels pretty fast, noticeably faster with the dr. box on.

 

I would say I bought it in June or so, the codes were never a problem until I put the bigger rubber on it.............. What is there warranty???????

 

1 year if you send in the warranty form I believe is what it was, or if you didnt 90 day electronics warranty.
