So I made my weekly trip to LANCASTER DDRAGWAY in western NY. Right off the trailer I ran an all time best of 7.21 @ 96mph. The car preceded to run slower every run thereafter.

run 2: 7.28 @ 94
run 3: 7.31 @ 92
run 4: 7.37 @ 92
run 5: 7.41 @ 92

After the end of run 4 as I was slowing I heard a loud pop like a m-80 going off. It kinda shook the car and scared the crap out of me. I thought I blew a HG or an intercooler pipe. Back in the pits I gave the car a thorough lookover and found nothing wrong. I was already concerned about the car slowing each run and now this happened. so on run 5 I was very tentative and ran the7.41. so the car still slowed some but mechanically seemed fine. Eliminations were starting and I dialed in at 7.40. I had a slight advantage in reaction time .561 to his .572 I was ahead the entire race and let off on the throttle before the MPH timers and coasted through the finish line. I glanced up to see the win light come on in the other lane. I broke out 7.40 / 7.33 and lost first round. I fully expected the car to run a little slower. But on the last pass I'm sure it would have run in the 7.20's if I hadn't let off it.

I am attaching PL files I'm open to all comments or advice.
Please notice the RPM and BOOST at 0 MPH everyone asks how I do it? I have no clue if it's normal or something wrong?

Thanks for looking

Our builds are very similar except the turbo, and my data shows the same thing with the boost. Your 1-2 shift looks kinda high but maybe that's due to the turbo pushing it? What was your 60' time? Last year I ran a 7.3 and the 60' was a 1.66

First pass the car water temperature was good and just kept climbing along with air temperature
Were you hot lapping? This can slow a car down . I try to keep water and under hood temperature as low as possible. Been thinking of taking my leaf blower, racers raise there hoods to lit heat out , I do for a little bit just checking oil water and a quick check and leave it up about 10 minutes.
I have a question, I seldom use my 2Step our go WFO for 3.5-4 seconds like you do ,is this normal starting line practice? Your turbo is way bigger than my 5857 is this why?
