I am a noob, so please try to keep responses simple

Evo X gsr:
eibach lowering springs
speed circuit smooth cbe
cobb ap
ets licp
k&n drop in filter

Are there any other important mods that are recommended for optimal performance gains that aren't too pricey? How much hp/tq would you assume the evo would have after these mods? Also, would I need a gauge or boost controller or would the cobb ap do the job? Thanks!

 

Cobb ap will do the job for now for boost gauge.

i would say with a tune you are looking around 300whp

i would def get a test pipe, downpipe, uicp, fmic, and 3port boost controller

 

UICP. LICP is not very necessary from what I have been reading.

 

The best bang for the buck mods are a test pipe, air filter, and a tune. For the tune I would just get a Cobb AP and run an off the shelf program. When you're set buying all the performance parts you want, then get a pro tune.

I suggest getting a wideband O2 gauge. For $160 it's a good investment.
