Tried the stock one first couldn't lean my 660 out enough. Even with the gain all the way a 5 o'clock.

Switch to the 550 chip and it was fine.
just want to let every one know just in case they want to get a vpc and have 660 or bigger injectors to control.
 
Thanks for the info! Are you using anything else in conjuntion with the vpc? GCC, AFC, AFR??
I've got a VPC/GCC combo with 650 injectors and the Buschur 660 chip and love it!
 
I have an HKS AFR.

I'm really happ with it.

If you have the VPC gain at 5 o clock its at full rich. 7 is full lean.
 
Sorry about that I was ment to say 7 O'clock.
