No, the 550cc is at 55 psi. At 3-bar it's more like 480cc/min (stock is like 410cc at 3bar)

Eurocharged is scheduled to retune me (remotely) on Friday.

Any update on how you have made out with the injector install and retune ??
Re: Stacked pulleys - 23 psi with no codes. :)
I sold the mid pulley and I'm having a new pulley machined this week. I really want to stick with my original plan of running 22psi (not 23). After the pulley is completed and installed, I'll get a retune to see if the stock injectors and SL55 fuel pump will keep up.
If I'm still lean at that point, I plan to install a larger fuel pump. I really don't want to install larger injectors if I can help it.

Good luck.

Good luck.
5MM = 3 psi
1MM = .6 psi
3.33MM = 2 psi
Re: Stacked pulleys - 23 psi with no codes. :)
I finally got the 2psi (-3.33MM) pulley back from the machine shop (Bullard). This time they only charged me $140, since they are making quick work of it now.
I bolted it on and drove a few miles today to make sure it was engaging properly and not making any noise. The power is great and my new tires are getting it to the ground without excessive spin.
Tomorrow, barring a rainstorm (which is in the forecast), I'll datalog 2nd, then 3rd gear to see where the timing, fuel, and IAT's are.
After that I'll get a retune if I'm lean up top.

I should know this but, what intercooler pump do you have? My additional heat exchanger experiment isn't working out but I have the stock weak-a@@ pump. The knock on higher boost has always been the extra heat, as you know. Do you have the thermal coated I/C? I WANT ONE! I'm taking notes in case you didn't notice.

I'm running the CM30. As for the I/C, it isn't wrapped yet, but that's on the list.

And I thought I was first!? Been stacked for over 3 years now.
Of course there was that one little incident! (see towards bottom of thread)

I'm definitely not the first with a stacked setup, but I suspect I might one of a few hitting 22/23psi at sea level.
