cts2 or diablo tuner
 

hi, i like to buy a performance tuner for tire size chage, gear ration, etc. Evoution CTS2 or Diablo? whats your opinion? thanks

I have the Diablo and have been happy with it...

Blackbear performance, have Justin hook you up. Well pleased with their offering.

I also have a Diablo Intune...... Been very happy with it. Once you get it, if you want to go beyond the built in tunes you can contact Lew and get a custom tune done too which is also worth it.

Another option as Baldfox mentioned is getting with Justin at Blackbear and get him to do a custom tune. Both are excellent, well proven, and well regarded options for remote custom tunes.

thank you guys. so you all recommend custom tuning by a specialist? i incline to get diablo T1000. thank you

hi, how can i get in touch with Lew to custom tune?

Lewis is a good guy to deal with. He will send you instructions and if desired you can also buy the tuner itself through him. He is well known by Diablo Sport.

The difference between the standard tunes and a custom one is pretty dramatic and yes - I highly recommend it either through Lew or through Black Bear. You can find tons of nothing but accolades and praise for both of them in the various GM truck forums.

thank you, i will call him for custom tuning.
