A very big YES! The 91 octane tune is better than stock as far as power, the car doesn't fall on it's face between shifts like it used to and the car pulls like a beast to the NEW 7000 rpm limit. I'd say it is very much worth the money, IMHO.So are those that purchased this product for 500.00 or so, happy with the gains on the 91 oct map(s) ?
I live in Canada where 93 is not available
Also what I'm really having difficulty with, is risking the mfgs warranty by installing this product :scared:
