I like it!

My advice: Spray lots.

Haha That's what I intend to do!

I have been wondering about what the limits of what you can spray on Ls motors is though. I am curious if doubling N/A hp output on spray will be an easy or daunting task....

clean truck.. i like it.

as for the nitrous, make sure you do a wet shot. change your plugs, and pull timing.

also that Rob guy... I'd be weary of him... he's into some weird ****

yeah, ill try to keep him at arms distance, even tho hes got a pretty sexy truck lol

I was actually planning on a wet shot , and have the hardware to do so...

but I have always been a bit afraid to put fuel into an efi intake and recently I learned about how to use a dry shot...

So I realized how easy it is to use the sock computer to add fuel and pull timing by witching the IAT or ECT to some resistors with some relays...

have any experience with this method?

I have a lot of experience with the IAT timing trick. I ran it when I had nitrous. Worked flawlessly. I think I talk about it a little in my build thread..

And yeah I've known Jake for a long time, same with Alex, who I assume is the friend who introduced you to our lovely Robert.

Yeah Alex is a co worker and friend.

So as for the IAT, I see there is also a table called initial adder vs IAT.
Can I use this table to bump up the commanded afr to produce the fuel enrichment when spraying?

Thats a question for the tuning experts... I ran a wet shot, so I just pulled timing thru the IAT

You could, yes.

You would show an AFR error through those cells while data logging though. If your VE is dialed in and then you suddenly inject air and simply command a fatter fuel ratio you could get it where you want, but the computer will recognize it as leaner than you are commanding. I don't necessarily see a problem with that, but I think I would rather do a wet shot.
