I recently purchased a 2003 Evo and I am excited as hell. Here are the mods:

GT30 Turbo, HKS 272 Cams, Ported exhaust manifold, perrin down pipe 3" stainless exhaust, intake, buscher fmic, piping, 780cc injectors, adjustable rear sway bar, meth injection (currently unhooked) N20 Intercooler sprayer.

The car pulls fairly hard but I don't think I am reaching its full potential. I am not interested in adding anymore power mods. Currently the idle fluctuates. I imagine this is due to the ECU not used to cams. But I am a total noob so I am not sure.

If anyone has any tips or advice I will be much obliged. I am fairly new to all this. I am thinking the tune needs some tweaking but I would like some feedback!

Thanks!

 

I'd get a tune by a shop with a good Evo reputation asap and ditch the meth kit. Congrats!

 

I'm sure you can get that idle under control with a better tune. I like the sound of a cam with some lope to it, that's me tho.

 

Congrats! Get it checked out by performance shop n enjoy your new toy

 

grats in the new ride

 

Thanks everyone!

 

Congrats on the purchase. Hook up the meth kit and have some fun!

 

I say sell the Methanol Kit. And don't let NICK drive it!!!

 

Excellent! I need to see it sometime.

 

Congrats.

Get what ever parts you are going to install and get an new tune.

 

Nice.

Make sure all maintenance is up to date ie. timing belt and get a tune. That should take care of the idle unless you have a boost leak.

 

Plan for some track time and really have fun with it!

 

@detroitms3 where did you get your tuned?

 

It was tuned somewhere in Texas before I bought the car. I've never been able to get the name of the shop though.

 

Congrats!! And like everybody else said, I would take it to a shop and get a new tune!!
