Here's his dyno results @10psi. All stock except drop in K&N and Forge BPV. Good numbers considering he has plenty of room to play with according to his A/F numbers. Congrats BLU!

ok a/f reads as the higher the number the leaner u are. idea for turbo is around 11 to 12 depends on tune. 13 something is stoich which is prime for n/a motors. 11 to 12 is prime for f/i motors which need to run richer, everyone has a differnt idea on the 11 or 12 for the f/i cars.

That is similar to what I want to do. K&N Panel, JoeP at 9-10psi. I wonder, did he change his spark plugs?

I figure I should get a little extra power and stay safe with cooler plugs and 9psi with the rest stock. I don't have a couple of grand to spend while I am still making payments on the car.

Just to let you know...14.7:1 is considered "STOICH"
Just a little FYI.
