My new HPS post MAF tubes installed

6spd

ive got the s-tune exhaust right now, along with the filters and tubes. I love the way the car feels/sounds/drives/etc. I wont go back to the FI. As far as a/f goes, with bolt ons, you wont have to worry as pretty much all the dynos we see have fine ratios, not perfect, but fine enough for general use. tuning will change the dynamics of the computer with respect to timing, fuel delivery, etc. to achieve a perfect a/f ratio and maximum power. you can, though, put your cbe, cai and hfc's on without a tune without a problem, but if you want to suck every available bit of power out of the motor with that setup, you'll need a tune.

btw, my name is JJ, haha, yours too?
