Now that I have some time in the car, I have to say that it's a tossup in my mind whether the ECU tune from InMotion or the new TVT injectors made the single biggest improvement in the power of my NA Xfire.....but with BOTH this thing is awesome, very smooth all the way up the rev range, pulling strongly the whole way. I can even feel it in the mid-range (say 3500 and up).

You know you did something when you take your girlfriend out in the car and she say, WHOA what did you do to it this time ??

 

hey, can you let us know what these changes have done to your milage?

 

Haven't checked yet, and it will be fuel dependent.........I often run a mix of premium (91 they say but Phoenix gas sucks due to the anti-pollution add-ins) and the 100 octane racing gas --- car runs great, the racing gas is $7.25 per gallon. Luckily it doesn't take a whole lot to make a difference.

 

tazz, theres going to be a Midnight Madness coming up at the Tucson SIR drag strip! You should see if you can make it down here. ill find out the details if your interested.

 

Is that the drifting event ???? I wanted to go, but have other things that are more of a priority........

 

no just 1/4 mile but that would be sweet if it were drift. i dont think id enter but itd be very entertaining to watch amatuers beat the hell out of their cars.!
