I have a 06 GT that I have installed shorty headers, cold air intake and 62mm throttle body, all from BBK. When I installed the throttle body a few days back I also installed a performance tune for 87 octane with my diablosport. Is the perfromance tune good enough to keep my engine happy with the changes I have made? My concern is leaning out the motor. Should I be using a different tune? Some time soon I will be installing 4.10 gears and might install NOS. Any suggestions?

 

Your tune from diablosport will be fine just as long as you enter all the upgrades you listed into your tune. I would put in a 93 tune for more power at the track (if you go). Your best bet is to go to a dyno shop and have them do a custom to so that they can play with you air/fuel ratio. Also get a air/fuel gauge if you want to make sure that you are in a safe range at all times. This really isnt too nessary but if your going to add any kind of power adder (nitrous,supercharger,etc) then I would get you a a/f gauge.

 

you need to jump on a dyno and make sure all is well with the AF. You're letting more air in than before. May need a little fuel curve adjustment. I've never been happy with a Diablo tune out of the box. Goo ruck.
