So I ended up running 30psi on pump with w/m sprayin on the way home from H20.....
Duty cycle was needing lots of tweaking all rainy weekend, due to barometric pressure and humidity. I have noticed I have about a 8% range depending on the conditions. Well anyways....Long story short is that Stg3 S4 was 3+ car lengths behind by the end of this 3rd gear pull and I kept pulling on him into 4th.
So I am going to do some logs and see just how much timing pull I have at 30psi, I have a feeling I could be doing this on the daily
I don't run wicked timing, which is great for this.

Doesn't hurt that I build BOOST right quick either

Sorry I am tired translate please.... what boost level @ what rpm?
I believe you have 8.5 compression yes no? You very well may be able to run 28-30psi on pump.
I am looking to at least

I have 20psi at 4200rpm. I hit 30psi at about 5400 and had it through till redline.....
I wasn't going to keep going past 6800 on 30psi. I do have 8:5:1, and a very safe tune timing wise.

I have a S258 compressor wheel crammed into a S256 with a .55a/r.....
<ul><li><a href="http://www.youtube.com/user/bassed2pt0">My videos on youtube incase you've not seen them. The open Dump and this turbo are loud as hell, think of a F18 taking off. Everyone tells me it's rediculously loud, but I like it.</a></li></

nice. Mine to date has been later than that. I am hoping some fixes will move it
Also wondering if the surge ports on your turbo made the difference up. I'm 1000rpms later on my dyno plots
