Right now I have I/H/E/P. Would it be worth while to upgrade my fuel rail, injectors, get e-manage, and get it tuned? I assume I will see a HP increase but for the money spent is it worth it? I do plan on going Turbo and will have to upgrade the fuel system and get e-manage anyway, so it wouldn't be a complete waste of money.

No, just wait to get it all at once. You don't need any more fuel with your current set up.

It wouldn't serve any purpose. You need more induction to have to upgrade the fuel system. I was about to do the same thing found out that I would be running rich if I did that.

What about just an e-manage with a tune?

No get a supercharger now and that will be money well spent.

engine management will always help pull the most horsepower outta your mods

No get a supercharger now and that will be money well spent.

Nah I am definately going turbo.

good supercharger sucks

if you're going turbo, then all the parts you listed above, i/h/e/p, are all a waste of money

I agree go turbo! Vroom...Vroom...more power!!! Always better. I'd say save your money and get it all at once.

Yeah I know that the I/H is a waste because they will be no good for the turbo. But I am not planning on getting the turbo for another year or two and I had to do something, lol. I think I will just get the e-manage ultimate, cause I will need it for the turbo anyway, and get it tuned and go from there until the turbo goes in.
