Yeah apparently they wised up and switched the kit from IWG to EWG. Too late now, I love my PTUNING kit.

So I got the car back and am EXTREMELY happy with how this thing feels. Drives beautifully now. Putting down 315whp on 93. Went back to stock injectors. Some diagnostic work has determined I have some minor mechanical issues with how my turbo system is set up. Hal at Dynosty is having to add a bunch of boost control after the initial boost spike to maintain 8psi with a 10psi wastegate. Running 60% duty on the EBCS doesn't make sense to see what we are seeing so we are both pointing our fingers at the recirc valve. I have a stable tune with overboost protection built in now, so the plan is to 1: add a vacuum distribution block and 2: install a new BOV in the charge pipe with a new MAF plate near the throttlebody. Then Ill go back and have Hal take another shot at it.

Debating now if I even need e85 with the numbers Im putting down.

Updated with a digital dyno sheet.

Why would you want to run 8psi when you could run 10?

Didn't say I wanted to run at 8. Looking at a BOVs right now to fix this mechanical issue Im having.

Looks like I will be buying this for my EFR recirc.

Its pretty jenky and might be the culprit. Will snap pictures tomorrow. I have a Treadstone vacuum block that is going on this weekend.

So 2015 that plot. Looks really good. I bet the car is tons of fun to drive and the boys at Dynosty are great.

Good that you got a result.

With the recirc valve, go to a scrap yard and get some brake line. Run that and just use rubber/silicone hose at the joins. If you can, also run the recirc line off the plenum on its own dedicated line.
It needs to have a stable and strong feed and if you have other things which bleed or pulse the boost/vacuum signal on that line, you may end up with problems.

EUREKA!

It was all in the junk OE recirc valve that was leaking/not engaging properly. Installed a new TurboSmart Plumb Back BOV. See photos below. @King Tut Im so happy right now! I did an EVAP delete, and routed the the under manifold vacuum port straight to the recirc valve. Boost comes on stronger, at earlier RPMs, and consistently.

I am recommending that anyone running an EFR with integrated BOV to upgrade to this little gizmo. It works splendidly.

Side note: I discovered some oil on the throttle body even though Im running a dual catch can setup :/ Ill have to do some digging there.

Thanks for everyone's help! Back to Dynosty for more fine tuning and ethanol!

Oil :/


Managed to do everything with just unbolting the TB. Didnt have to touch the AC comp.




Reused the OEM rubber line coming off the bottom of the intake, clocked 180deg to account for the elbow. Used a barbed splice and some new 7/32" rubber vacuum line to get it to the BOV. Notice the blue zip tie at the barb. kinda hard to see.




See you later sucker.



No idea why that spring is rusting. I think its an indication of it not working right and leaking boost.




New parts! WOOOOO

Congrats. Is the new recirculation valve a rebuildable/tunable unit like a Forge or Tial is?

The Plumb Back unit I have is rebuildable, yes. Tunable, no. The dual port unit is rebuildable as well and you can increase or decrease spring pressure to fine tune its function but it is fixed at 50/50% BOV/recirc.

See pic of the dual port:
