im putting in hks 280's this weekend and was wondering do you need a tune. I know you need a tune to get the most power. But was wondering if you can drive the car prior to getting it on a dyno.

any other tips on install are welcome.

 

Driving it is fine. Turn the boost down or just down get into boost.

 

I drove mine for a week without a tune but I babied it that whole time. I never went past 10 psi

 

if you put them in it is fine to drive it, just stay off the boost. I currently need a tune as well after the cam install I try not to go more than 2lb of boost. Riding sucks but you can move around, going uphill is the hardest part

 

do you have to have cam gears with the 280's i heard you dont have to but to get the most out of the cams you should get them.

 

im about to install cam too do you have to have the timing belt tool from mitsu. Or can you get one at an auto parts store like auto zone

 

I got mine from AMS. Its half the price of the dealer and worth it in the long run. You will need it in the future anyways when you change the timing belt
