I was wondering if anyone has used a handheld tuner on a 2010 gt that is all stock. I would like to know if it's worth getting since I plan on keeping it all stock.

 

If you are referring to a hand held SCT Xcal3 tuner with custom tunes, then "Yes", it is worth getting! Adding CAI will help add more HP, however, most of the performace gain is mainly from the custom tune (not canned).

 

+1 what kevin said.

What's your intent? Adding a good custom tune to a '10 will result in almost the same RWHP as an 05-09 with an equivalent tune plus a CAI. Add the CAI for a few minor RWHP to match the 05-09s.

 

I'm just looking to to get a little more pep. This car is my dd and I will never take it to the track(no tracks near where I live). Once in a while I like to slam on the gas but it usually has some lag. Also would my 0-60 time increase any with a tune? I'm not interested in getting a cai because I've heard that the stock one is pretty good. Also just bought a new home, and any extra money will be spent for projects around the house. Thanks for everyones help.
P.S onegoal is a turd.

 

If you are looking for a little more pep, throttle response and eliminate the lag, a SCT xcal3 tuner and custom tune is what you need. ;-)
FYI, Brenspeed and American Muscle/Bama Tunes are both very reputable companies. They do great work and have excellent customer service!
