I noticed that which is why I was wondering if it was the BPV, I can still hear that fluttering sound. I don't know... at some point when money is plentiful (yeah right) maybe i'll get a protune, but if this dyno is actually pretty on par with a dynojet, how much more power would I really gain for 500.00? Probably not even worth it.

The sound is likely just wastegate flutter. Eric's ok with that oscillation?Originally Posted by Methodical4u

The flutter has nothing to do with the oscillation. I wouldn't leave an oscillation like that. As a customer, you should ask him to fix it. It's not like a .5PSI variance, it dips 2PSI / 1PSI; the boost tables need to be reworked.Originally Posted by Methodical4u
How do the part-throttle logs look?

this was the first map he sent... I guess there was something with the fuel he didn't like, though it made a bit more power.

He just sent me a touched up map... i'll check it out, but i'm sure it's fine.

A dyno plot needs to be WOT. Have you not been sending him part-throttle logs, as well? I'm assuming you don't drive WOT everywhere you go.Originally Posted by Methodical4u

Got virtual dyno for the stage 2 map that you had on before?
im waiting on my pw tmic and ebc from rsd and will being going "stage3" . cant wait. im currently tp stage 2 k&n intake, cobb dp, nameless 5". if you went from stage 2 how does it feel?
boost is like alcohol, its fun and great in moderation, to much and something's gonna go boom.
Methodical, are you running 91 or 93 octane fuel? 370 is an impressive torque number. I just put my Perrin TMIC on yesterday and I'm waiting for my ebcs to get here so I can flash over to the TP stage 3.5 map. Sadly there's no 93 in CO.....
