Grip Grip, I'm still running very rich. I need to log a few runs and let you look at them. I can only datalog AFR with the MTX-L that you recommended since I haven't added anything else to the mix. I am hitting low 10's AFR but need to log to see what its doing in the top of third. It would be nice to add a little boost to see if I can lean up that way. My fuel pressure is luckily naturally high at 62 psi. I guess I got a good stock filter/regulator. I know Jerry tuned me pretty rich as I thought I was lean cutting out before the tune. It wasn't lean just cutting out,my DIY intake was vibrating on the coil packs. Dummy mistake. So I got a rich tune to start with and nice high fuel pressure. I'm definitely in the safe area mixture wise.

I have noticed something strange the last week. At steady cruise, I have always ran at 14.7-14.8 but started reading 14.9-15.0. Kinda wonder if my filter is stopping up. Haven't changed anything, but I did let the tank run pretty empty a couple of times before fillng up. Full throttle still shows very rich. Just typing this has me hopping to go make some runs. It feels like spring outside. 75 degrees...
