Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

[bottomline2000]

I have always been watching my a/f, that's the main reason for my dual function wideband. Previously, right after I installed the cam and headers, I was getting concerned because at WOT it was dropping to 10.3 which I considered lean. Boost went from 8 to 6 which I figured would happen since the blower was pushing the same amount of air but there was less restriction. Justin checked my data log and adjusted things and I went up to 11 which he said was about right. That's why I'm wondering why I went up to 12 after dropping pulley size and gaining boost back to the level I was at before. More air being pushed through should have resulted in a leaner condition, not richer. I'll keep an eye on it, and I'll be sending a data log to Justin. He did say previously that he allowed room for pulley changes to a certain degree with his tunes. I had discussed this pulley swap with him before I did it, and he instructed me what to do and what to watch out for. At least it looks like my fuel pump and injectors are adequate.

Actually 10 would be considered rich and what Justin did was lean the tune out to 11 which is ideal for boost. You had wiggle room before the adjustment. Now if 11 is leaner adding the pulley further leaned out the tune to 12 because of the added air. He will now need to add more fuel or richen thr tune to get you back into the safe zone.

The damn truck is going to feel faster afterwards. Luckily the lq4 is a low compression motor and gives you more room to play with boost.

I just looked through your whole build and you have a beautiful Denali man just WOW. Extremely well built nice work!

Oh yeah, I was thinking backwards again. Stupid brain. I'll send Justin the data log. Since he leaned it out before though, it does look like he'll be able to add fuel again without changing anything as far as fuel pump or injectors. I'll drive it easy until I get the new tune.

Lol, good luck with trying to drive it easy! I wouldn't be able to.

Maybe I'd better just put the other pulley back on lol. I just sent Justin the data log but I think they're busy right now.

I always just come in here and like everything you do red, half the time your talking craziness that has to do with going real fast, so thats a like for me. lol [emoji106]

I agree. Your mechanical acumen is far above my skillset in that department, but I sure like learning about new things and envision my Tahoe with an SC on there and giving some of the super cars around here a wake up call. For the moment, I will live vicariously through your thread. Pretty damn killer!!

I decided that this time around with the brakes I’m taking the easy way out when it comes to bleeding them so yesterday I ordered a Motive power bleeder, and today Amazon delivered it. Pressure instead of suction because I discovered the latter doesn’t work well.
