Somehow.....We had a bad transmission last year after the filter gasket became unseated and lost .13, but our MPH never budged, and your loosing both. That's a hundred horsepower your dropping. Do your headers look like they are getting hotter than normal? Like its baking the coatings ect?

Hey Jeff how you doing. I am one of the guys working on this car. The car sounds good in the pits and going down the track. Headers look fine so i don't think it's going lean. To be honest it's driving us crazy and thanks for the suggestion keep them coming BTW how's your brother and Amy doing

Hi Bill ! Amy is driving John nuts with all the virus stuff. She's absolutely ate up with it and John...is John. It is what it its LOL . But all is well up here.
On this guys car, I had a car last summer (Rich South) that had me look at his Holley system. I found a severe grounding problem. Its a long story but it also had a mismatch of "type verses set up" in the programming of the crank trigger. His car went from a 7 under car to a more than a second under car. Like yours, it didn't miss, didn't run bad, just did not run like the dyno said it was going to. I'm betting your going to find something like I did. Keep lookin
