these any good for a 01 mustang gt with a bbk TB, off-road X pipe, with flows?

thinking about getting one and setting it with the pre-tuned 93 octane tune, anything i have to know before i put it in?

also the cheapest place to get one, thanks!

 

No they suck, As do most tuners.... Get a custom tune

 

i dunno what he is talkin about but i have a diablo tuner and the tune it comes with is alright, i plan on getting an O/R H so i can use my bros wideband and truely tune my car some more but i feel its worth it. i have no speed limit and i turned traction control off permanently.

 

i got one. IMO it's worth it. cheapest place to buy one is ebay. i got mine brand new off there for just a lil over 300

 

what kind of gains did yall see.. i just orderd one for my car.

 

i got mine for my mach 1 about 2 weeks ago, got it from www.autoanything.com for 329 brand new, and it made a big difference you can really feel, not sure how much it did but it was a noticeable difference and my car is completely stock cept for a K&N drop in
