I was wondering what would be the best way to approach my situation. I swapped a 2018 l83/A8 into a c10 and the customer wanting more power went to another shop and they swapped the ecu to a l86/A8 and he is complaining that the truck doesn't run correctly. My tuner says it would be complicated to try and change all the tables over to the l83 specs. What would be the best option? I do have access to gm's sps software if needed. Thanks
