my car has never pulled like a freight train much past 5500 rpms. but sporadically, it would pull like hell through the lower revs, all the way from 1500 to 4500 can give a good strong acceleration.

i put the FMIC on yesterday, and now it's reversed. the turbos act real sheepish all the way up to 4500 or so, and then they pull like the freight train.

i still have the stock airbox. k&n air filter. does increasing the core size of your intercooler (the gain in air volume, i assume, impedes the airflow?) mean i have to push boost harder or do an intake mod?

or... is my n75 broken....

or... (i'm emailing about a copy of ECU-X right now)..

or is it possible a boost leak could be occurring at low boost pressure, and it goes away as higher boost pressure is requested..

stay tuned! cause by golly i'm going to find out.
