Custom tunes will yield much better results than those handhelds.

 

Do a search for "Westers" or "Nelsons" tune (on this site).....They will blow the doors off of anything Diablo or Hypertech can do for you.

 

Or there is also PCMforless.com (site sponsor)...Link to the left.

Wingnut is right on the $. A handheld program is better than nothing, but a custom tune will provide you with even greater performance at almost the same cost.
