I own a monte with a ls4 and my friend owns an impala with a Ls4 is it possible to tune both with one diablo tuner...or would you need individual ones. just want to know, so me and my boy could split the bill.

 

hmm... dont know about the diablo... but i would say look into the HP tuner and see if that tunes it. you will have much more control with that. or for the money buy a PCM from will at Overkill :: Overkill Motorsports :: he is great when it comes to tuned PCM's and prob one of the only ones out there that can tune your LS4.

the hand held tuners are so limited that it is just so much better to have a PCM made/ swapped in

 

Most hand helds ikn of only work on one vehicle at a time, id go with a pcm tune

 

Thanx for the input I well definitely look into it
