OK so i have, an 03 evo 8 with the following mods.

280 cams, new injectors,xede, green turbo, megan exhaust manifold, turbo back exhaust(no cat), new cam gears,ams fuel rail, boost controller, oil catch can, new intake, has stock intercooler wanting to put one on before tune but cash is low, should i wait till i get the new FMIC, and piping this could take a couple months or should i tune without. i

Thanks, also any numbers that i might
expect off of a dynojet would be appreciated.

 

you'll still make good power with the stock FMIC in this cold weather we're having but it's likely to suffer when it starts warming up outside or after multiple pulls.

can I ask why the xede and fuel rail upgrade?
