I'm having the opposite problem from dansrt4. I just street tuned mine to 20 psi and still am getting a MAX of 10.4 afr. I'm only pulling out 15% with the neo, any more and I start to see a 2.0-2.5 count of knock. Pulls like a son of a bitch but I would like to get the afrs at least into the low 11's. Right now I'm running about 42 psi static on the return line, have the 1:1 hooked up, 255 walbro and DW 650's for fuel.
Talked to my one buddy today and we think some of the problem might be the direct fit QW intercooler. I definately need to replace it to help with spool also. Full boost comes on around 3400-3500.
