Here is the VERY simple deal on this. Pro-Stock motors are VERY specific animals and few people know a LOT about tuning them really. Some of these teams have hired and fired some of the BEST EFI tuners on the planet. The difference is, these guys don't KNOW Pro-Stock motors. Now these tuners can and WILL figure it out, but patience is NOT a virtue in this class...............Now on the flip side, you have a guy like Jason Line who knows Pro-Stock motors in and out, PLUS, he caught on to the EFI thing VERY quickly. They SHOULD be way ahead and are. Hard to tune something you know nothing about and go right to the front.

I tune a LOT of EFI stuff. Could I immediately take a turbo car with the same stuff and make it run as fast as Steve Petty does........ hell NO. Might figure it out eventually, but might take a while. On the flip side, Steve Petty is likely the best turbo tuner on the planet. Would he expect to take a Pro-Nitrous car to the front the first time he touched it......NO. Then you have great all around tuners like Shane T, the guys at EFI University and others. NONE of those people have EVER tuned an EFI Pro-Stock motor, because there has never been one. Going to take time

PLUS and this may be the biggest PLUS of all..........everyone is immediately thinking the EFI is the issue. Maybe, maybe not. It COULD be that the KB racing cars just found some HP, as Pro-Stock teams are prone to do from season to season. They have done it before, Elite did it for a couple years. Mike Edwards was the "man" for a couple years and so on.
