Here's a video from today with a sound clip of idle. I was out tuning part throttle and rolled into it in second gear as well. It spools quick!

The streets are wet and cold here so I'll get more data on the muffler come spring. So far I've gotta good idle results. I was hoping for a few less decibels at cruising speeds (35-40) mph. You have to speak up a little while cruising in my car, but I suppose having a vert doesn't help either..
The next stage is to sneak an electric dump just before the muffler for when I have it tuned to 20lbs. I have a front mount and I ran my exhaust all the way back to the bumper.

ID850's and ECS fuel system came yesterday. Not it a rush to get it done though since we just got snow. Will get this installed and report back once I can take it out and finally do some tuning past 4psi.

Update....
Started street tuning with the ID850's and ECS Stage 1 fuel system. I also installed an AEM wideband and an AEM Tru Boost controller.
With the boost controller and running on the WG spring it's making 5psi (5psi spring). With boost controller on "A" setting I have it at 7-8 psi (45% duty cycle) and on "B" setting I'm seeing 10-11psi (65% duty cycle).
I have timing at 14 degrees and AFR set at 11.3:1 on 93 pump gas. It pulls like a freight train and has no problem making boost! I plan to put a meth kit on it and finish tuning but for the most part this project is done.
Video of 3rd gear pull. AFR was close to 10:1 here but you get the idea..
