handheld programmer
If you have an automatic --trans tuning alone can make your car quicker without touching anything on the motor !! But most handheld have limited access to the nearly 250 tranmission tables--TQ mangement delete-- and a " generic" shift firmness setting"
IN my opinion the best of the handhelds in the Diablo --I gives you more options for engine and transmission tuning --and allows you to make changes beyond the pre-programmed included tune setings
IF your engine is modded beyond just bolt ons--like cams/heads/LT headers---any handheld will not address enough tables to get the idle and surging problems sorted out and you would need a full tuner such as HP or EFILIVE --again the Diablo handheld would come the closest to tune a modded engine but it may or may not cover all the bases--
Handhelds now range from the $350-$450 range--- But you could get HP or EFILIVE with enough licenses to do 2 vehicles for around $750--
If you are planning ANY future mods---it would be best to wait and get a full tuner---There is more of a learning curve involved with a full tuner--You must have old school engine knowledge and know your way around a computer and like to "tinker"--and have patience
and, you can also get custom tuning done for it by a diablosport CMR custom tuner...

To me, the price of a used one was worth it to make these changes alone.








I'd like a good answer to this, as well.
