Any reviews about Diablotoona? Considering them for a follow up Tune to address a "Too Lean" error. SSi Performance isn't returning my calls.
Do you mean DiabloSport? A better and safer option is to use HP tuner. It is not a handheld, like Diablo, but software that tuners use- each tune is custom.
If you're certain there's been no after market tuning adjustments made then you can proceed with anyone's product. HP Tuners is more versatile (can read a Diablosport and other's tunes) but more expensive.
The 'too lean error' was due to the first custom tune. (Factory was fine.) Shawn sent me a 2nd tune to fix it. Didn't work. Then when ghosted me. So we're trying someone else.
With the HP Tuner you can save a copy of a previous or factory tune and change it back in situations like this. You must be using a device already if your applying different tunes (assuming your not sending the entire ECM)?
