I have run the Looney tunes/ Vivians tunes for 7 years. I am wanting to try some other tuning just for the hell of it. I have looked into gearhead and php. I have run IDP tunes also. Who do you recommend?
IDP or Gearhead is who I would suggest. I run IDP with no problems and customer service has always been great. The other tune I'm curious on the TSD tunes.
I run the 8k tow most of the time on my gearhead. I put 20k miles on the Extreme SRL tune last year with no issues what so ever. transmission is still on point
