2-3 takes for ever to shift on spray
. the issue was completly unrelated to the clutch packs also so the method i describe is pretty safe if you are careful.the way i got it the best was lowering the rpm table for the shift points out of the picture and using mph to find the correct shift point. spray makes the converter stall higher/slip more so it can mess with the rpm settings, as i have a completly different bin. file for nitrous.
