I just finished putting an EVO X intercooler on my 2009 Ralliart. When driving around my rpm's will jump 500-700 all of a sudden. Boost kicks in...and a few second later my rpm's jump up (not because of the boost lol) I'm due for a transmission change, waiting on oil to come in...hopefully Tuesday. RPM's have always acted strange, but seems to be a normal thing according to everything I read. Not sure if it's because of the intercooler and it might be more noticeable than it was, transmission or ???
