I did not think the few mods I have and am considering would require more fuel.
1. Who dyno tunes Mercedes?
2. I might just consider a Kenne-Bell boost-a-pump for additional fuel. 1lb. increase for each lb. of additional boost. It is the dyno tune that has me confused. Did Jerry do the tune over your laptop or work with the owner/operator of the dyno? What AFR's are considered good for these motors, 11.3-11.5:1?
