Does anyone have auto enginuity and live in Southern California?

I got my truck tuned and running great the only problem I have is my speedo is off. I’m on a 10” lift on 40’s with 4:88’s. I’ve tried several shops but no one has the program to go up to 40’s. I have an 8 position chip and was curious if it will wipe out my tunes when changing the tire size with AE? So I was curious if there was anyone in Southern California who has it and could help me out with that. Other thing I was looking at is if anyone used the Superlift Truspeed and if it works? Thank you

I used the Truspeed and it worked great, this was back in 2002 or 2003. Sold the truck in 2008 and no issues with it in the 5 or 6 years I had it.

Ok now I just have to find one. So far the ones I found are going for $600 plus and that’s not going to happen

Download forscan and do it for free. Here is a good how to. Seeing how you have bigger then 35s, youll need to adjust the revs and the tone ring get the speedo right. It also wont have any effect on your tunes.
