I think its the defueling but not sure? Truck pulls hard after every shift but the cars/ trucks i'm racing just seems smooth. After every shift I always catch back up to whom I'm racing??? How do you take care of this with EFI? Thanks for your help.

Are you logging with the v2 or your laptop? Latest software?

With my laptop. To log with my v2 do I need a memory card. My HP Die's too Fast.
And now I'm thinking it could be the 4-5 shifts? I had reset the taps so I will have to see after she relearns. The hard part is like a lot of people my truck is a work truck, DD and tows every week and I pull my trailor to the strip with all tools, race tires and generators ......
