im currently running the Greddy IC.i Plan on upgrading to the ETS RACE FMIC,and possibly a buschur ported stock intake manifold.how bad will this throw off my tune?

im in hawaii where AEM tuners are very rare..i know 2 of them but they dont work at any shops and work all the time and ones about to move.

im probably just gonna go with the IC for now,im thinking the intake manifold will throw my tune off.

also i put down 418awhp.since my dyno i installed a new clutch,resurfaced flywheel,and a buschur UICP..now with the ETS race fmic what you think i can put down on same 22psi?the greddy is about 3.2in i think.already felt a difference with the clutch and uicp.

thanks

 

the fmic would be fine for your tune, and the stock ported mani would probably be fine also. i'd contact buschur about it, since you want work done from them anyways

 

The new clutch will put more to the ground, but not much. Would be more with a lightened Flywheel. Or at least that what Sport Compact said about their Project Car.

The UICP may not change much because they're similar designs, but the FMIC may give you 3-5AWHP

 

More about this...

Having a new intake manifold will possibly change your powerband a bit. I would definately reccomend a tune.

Hell, I'd recommend a tune when changing anything except oil or oil/air filters.

 

Oops... slow *** work internet.

 

My AFR changed a decent amount when I swapped out FMICs, manifold and 02 housing.

 

Get it retuned. Better safe then sorry.
