Warm start drivability issue.
I have a 2015 5.0 Whipple 2.9L and I'm having a very specific problem in my tune. It occurs after a warm start. Lets say I drive to town and go into a store to shop. When I come out the car starts fine, but when I start to drive off it feels like I'm towing a camper. The exhaust is louder than normal and the car has no power for a few seconds and then it quiets down and runs normally. Sometimes I can also rev the engine a couple times before driving and it won't do it. Any ideas?
