Is it worth going from revo stage 1 to revo stage 2?
 

I'm wondering if folks feel if there is a noticable difference between the two. Also, is an intercooler required?

Cheers

is the sky blue? is audi german?
 

moving up a stage will always give you noticable gains, no matter who the tuner is...as far as an intercooler goes, i do not believe it is required, though always recommended if driving in warmer/hot climates...if you're in an area that's cooling off for winter you should be fine though

Look a few threads below and ask Arun for yourself...

I guess that's a big YES, then.

IC alway good idea. especially in hot areas.But the upgrade is like getting chipped again.
