My tuning. No correction. Everyone was 30-40 off from what they usually do. It was only 40º so that probably played a part. I'm very happy with it but I'll know what its really making at the dragstrip. Pulse was 2500µs. Timing at 26º. Max Boost 35 psi. I think it has some more left in it. Got some video to upload shortly.

Thanks everyone. Track opens on the 16th now. They postponed it due to the crappy weather and upgrades they made. I'll know what she has in 13 days. I'm anxious as hell.

Nice :thumb: stock sticks?
Nice numbers. What size injectors?

ExtrudeHone 40%. I got paranoid and took everything out of my sig after Wendy got stolen. :eek:

Josh, I want to thank you very very much for your timing calculator. It has helped me out tremendously. I was pretty much guessing before I started using it. You're the man!

I was there and saw your truck run. Congrats on the great #'s

Thanks. You're Bills friend right? I heard your truck and came running in to see what all the noise was about. Congrats on your runs too! Did you end up winning?

Thanks guys. I'm happy with it.
I almost forgot....Max EGTs were 1400º. It moved fast but the needle just hung out there.
I think Operation:Airflow was a relative success. :D

I'm glad the timing calculator was helpful to you.

So did you do any other airflow mods along with the turbo? (boost tubes, grid heater delete, intake, manifolds/up pipes, etc)

Josh, just wondering what's your theory on having the fuel pressure table on the calculator? Whatever the reasoning that thing is silly handy. I use it a bunch, less now that I have a pretty good selection of tunes made but pretty much all of them have your fingerprint on them.

Yes. Banks Boost tube, Profab Up pipes, EGR delete and downpipe. It already had an AEM intake for a few years. I still need to get a upgraded manifold for the drivers side.

The pulse width changes with fuel pressure. It was necessary to determine the pulse width that would be used for different fuel quantities at different RPMs.

Who's EGR delete tube did you use? I'm asking because I have a friend who has the same turbo, and he is always asking me what upgrades he should do next. You seem to have a pretty good setup, and I think it would help him out to know what kind of success others are having with the same turbo. He is only 2wd, but he was trapping a little over 107 in the 1/4 yesterday.

Aha. I had long wondered that. I hadn't thought about it other than pulse width vs rpm.
