I have the tuning guide and a strip kit. I don't think there have been any changes to the guide since I saw my first copy 20+ years ago. I already know that I'll probably have to lean out the primaries and fatten up the pump shot to get it across the hump. I got it close last season but it can be better. Not my first rodeo with a carterbrock. This is the first time that I feel confident enough to push the lean envelope with one though.
