Thanks again for the tune I noticed a difference after driving it around. It seems to have a stronger but smoother pull to high speeds. Much smoother on the highway, start up, regular driving, pretty much all around! I also noticed less fuel smell at idle so I guess it wasnt all exhaust. I got about 21.5 mixed city/hw driving last tank with the richness so I cant wait to see the next tank. I had a couple questions that I forgot, I told you I had hi flow cats because I had just bought one, currently I have an ORY pipe, well I got the catted pipe and it has bungs for the rear O2s, as far as I understand it, the rears dont affect the running anyway right, just check for clogged cat? I'll probably just plug them in to fill the hole and to look legit for inspection. Also is it true that you use less fuel engine braking rather than just going to neutral? I've heard how the theory works and that its been proven with data lodding and fuel cells etc. Have you ever tested this? Well thanks again.
