Which tuner

Sniper trumps all other tuners on the market.

Cars i have tunes with just sniper SF
99 gt with 150shot
04 gt 15lbs of boost from a D1-sc
01 gt NA
02 F150 NA

Learn a little about tuning and you will never have to waste money on a dyno tuner again.
 
Diablos were ok , until the new revision , now you cant even disable the rear o2s with the handhelds , you have to get a custom tune for that now , Sniper has more features for less money , dollar for dollar , I do free custom tunes if you get SF from me
 
I have the old-programmed Diablo and it did its job just fine.

I paid $175 used. I calibrated my gears, turned my CEL off from the exhaust, tuned my car and gained 6.9 rwhp and 13lbft OVER the canned Predator tune.

Well worth the money.
