They do??? I have never been impressed with how any S4 has run on Revo.

EPL stage 1 and stage 2 chips work great

Go with Giac X there are a few in the classifieds for around 400 bucks.

more aggresive.

Downside: decreased smoothness / partial throttle driveability.

as i understand i need stage 2 chip, what is the difference between them?

jprice@CPS

Stock: Stock ;-)

Stage 1: Chip only

Stage 2: Chip and exhaust

Stage 2+: Chip and exhaust with test pipes or high flow cats

Stage 3-: K04s, stock injectors, 5 bar fpr, 3- chip, stock MAF housing

Stage 3: K04s, larger injectors (usually with 4 bar fpr), larger MAF housing, stage 3 chip

Stage 3+: Stage 3 items with K04 hybrid turbos or RS6 turbos and tuning to support the higher capabilities of those turbos.

I'm not sure what to call a GT28RS S4 :-)

as i thought, stage 1 and stage 2 -> ECU chip the same, nice info on stages!

jprice@CPS

Usually same, some tuners have slight modifications for the 2.
