Yeah I did try the shuffle, and it didn't really help much. It got me wondering if I have a check valve on the brake booster like the last truck did. This brake booster assembly is a bit different so it may not have the valve.

Yes. I jetted it rich because I didn't have a perfect pair of jets to match the mixture right. The bottle heater was also taking a ****, so the hits were really soft. It went a whole point richer in AFR, so I'm sure that soaked up quite a bit of the additional power the nitrous provided...

I didn't say it was surprising.

Can't wait to see how it does once you get her all dialed in!

Can't wait either! Will post up the slip and videos tomorrow

This one takes more timing, as I have the better plugs in it. I can run 15 degrees, but after IATs heat up by about 3rd gear during a pass, I start seeing KR. I made the IAT spark table pull timing more aggressively to compensate. But spraying nitrous/meth mixture was able to kill all the KR too

Hopefully with the meth kit in, I will be able to run 18-20 degrees on 10psi.

I bet you don't have a check valve, my 05 crew cab didn't have one, push through at 1 psi. Put a check valve in the line, build 7psi easy

Btw, that's a pretty nice mph on that run. I'd say you did pretty good, especially since its your first run after such a complete tear down and rebuild of a different truck!

No, the other truck had a check valve built in. I assumed this truck did too.
