DSM 450cc and VAFC II - Not leaning out enough
Hey everyone,
Right now my car is at the shop being tuned at Autolink motorworks. The infamous Dr. Charles is tuning my ride. He did all the install work also. I had him install 450cc DSm injectors which I had cleaned and balanced, a VAFC II and a 255lph high pressure walbro in-tank. The problem is taht the VAFC II is not leaning the injectors out enough, he called me and said that the VAFC II was at
-50 across the board and my A/F was like 10.2, very rich. -50 is the MAX the VAFC can lean out. What is the problem? I have heard of numerous success stories with my set-up. Could it be caused by an improperly wired resistor box? Impoper VAFC II wiring job? Please help...need to know fast. Thanks

Re: DSM 450cc and VAFC II - Not leaning out enough (Hoodwinked)
*UPDATE*
Ok, I talked to Kitty (owner of Autolink) and she said that Charle's said it was a faulty missing link. He installed one of theirs and it is working better now. Could the missing link keep it from leaning out?

Ya, What is your fuel pressure now?
I belive the high pressure pumps are usually an inline style. If yours is an intank-high pressure pump that could be your problem. One of the cool things about the hack is that you don't need to run 2,3, or 4 times the stock pressure.
What about a stock gsr or type AARRRRR pump.
