Anyone tuned a Whipple 5.3? Customer has the kit installed and working. I don't like the piggy back fuel controller much. He has changed the cam in the truck and wants more power out of the combination along with fixing idle issues that can't be fixed with the handheld programmer that came with the charger kit. I'm running stock timing right now. I have removed all of the TQ management and raised the line pressures. If anyone has any suggestions for addtional changes on these kits, let me know. Thanks,
