I've searched with luck. I know I read about the adjustment screw under the bottom of the maf. The reason I ask is cause my injector is always off when I tune it. My 550 would have to be 330 to not be lean and my 1000cc are looking like the same thing. I noticed there is clear silicone on the screw. I'm thinking that the previous owner tried to adjust that for bigger injectors or pump to save money. Not sure but thinking either that or possibly a bad maf?? Wondering how much and which way to turn it. Possibly monitor the maf reading while at idle to check this.
