Guys,

Can I just install the heat exchanger and 2.80 pulley without tuning with the Diablo? Will the car run right without the tune? Also, with the right tune, how much increase in powercan I expect with just there upgrades? What will be the boost level with this pulley?

Thank you in advance.

i would deff. tune it just to be safe, plus it will be more efficient no matter what

Anything under maybe a 3.2" pulley, you DEFINATELY need a tune, even if it's a mail-order tune. And you will get about ~455rwhp.

I agree! Definately go with a tune! It will be much safer for the car! Also, I would go with a dyno tune aswell! With dyno tune you'll be balancing the air to fuel ratio!....Anyone correct me if i'm wrong, but a 2.8 pulley would be 14 lbs of boost.

you have to tune for that pulley swap

I Purchased a diablo tuner but have no experience using it. Will this thing walk me through it or do i need to find someone who knows exactly what to do?

Well if you want to be cheap, just get a mail-order tune. But if you want to do it right, bring it to a local tuner around your town, and get it dyno tuned.
