Best run to best run (both were single runs not backed by another 11.8@118+ with airbox or 11.5@120.5+ with all 3 mods) we are looking at a 11.85@118.37 vs 11.58@120.66 or a difference of: .27 seconds and 2.29mph.
Correcting the 11.85@118.37 to -700' (as the headers were run) assuming -200' for the RENNtech airbox and tune pass to start, we get 11.78@119.012 for tune & airboxes. Now compare that to the best + header pass of the night 11.58@120.66 and we see a .2 second and 1.65mph gain in the same air, same track, all things equal.
Respectable for sure, but not .4 and 4mph.

That's a .35 seconds and 2.75mph gain on average despite the DA being -500' better for the headers and mids.

I have only five runs on the new tune and headers, I have no doubt
the car will run faster.
Sadly, Island Dragway is closed for the winter. So, it's Atco for me
from now on, until I put my snow tires on.
I remember when I started running the car with just a tune and
DR's. I could only muster a 12.3 or a 12.4 and after a few weeks
the car ran an 11.94.
We'll see what the future holds.

That also means your car was prime to go as soon as you bolted the DRs on. You don't need 3 runs with drag radials, you need 3-4 runs for the ECU to adapt. You had "plenty" so scratch another potential excuse off the board.

....but humility is not one of your strong points and I think that
is why many members have a lack of respect for you.
Not trying to be disrespectful but just something I noticed over
the past few months.
Congrats on your 11.9 run.
You should be happy.Just a tip, next time keep all you your time slips and record them
for reference. Make notes on all your runs; weather, DA, track
conditions, launch rpm, dr's, street tires, etc. so you can see
what worked and what didn't.

Will do.
An 11.9 is very respectable for a tune only with DR's.

It would be!! I think that's a little involved more then a simple carbonio switch?? But try if you can it would be great to see some back to back runs on it.. Stay in the left lane over there

Yeah, that's true, it might be a little difficult to uninstall the RT and reinstall it.
