Prior to pfc install had usual 10-8-10 pattern although a bit spikey at wot in 3rd. My mods are listed below....just put in the apexi pfc, not tuned beyond base setup. I did not drive this hard and was not @ wot but did give it enough gas to drive the turbos up to 10 from 3k to 4500, then it dropped to 5 and stayed there. In 4th it is pulling 10 from 3k to above 4500....then i let off - doin' about 80 or 90 and not wanting to really push anything until i get it tuned and put the downpipe on....

any comments on what the 5-5 pattern is all about....i'm not very sharp on the turbo theory and do not have the commander option so i'm pretty much limited to my tach and boost gauge right now. I do have the manual boost controller installed in the ashtray but i haven't messed with it since i bought the car a few months ago.........


any comments appreciated....sorry for the longwinded message

Any thoughts at all??? If i was pulling ok before the pfc do you think it's just a matter of tuning????

ANybody have a similar experience with their pfc???

Get out the manual and adjust the duty cycle for boost control.

Thanks cewrx7r1....i did not get a manual with the pfc and do not have the commander but i do plan to get it dynoed soon so i guess that's when i'll attack it....but it sounds like it should be readily fixable...........

thanks.......
