so i have about 1,000mi on a .020 over rebuilt 22rte and i just pulled the plugs for the first time and it looks like it is running fairly lean, so am wondering how many teeth i should move the afm gear? P.S. the truck is stock other than being bored .020 over and LC Engineering EGR blockoff plates!

 

dont move it at all, mine were really white so i put a wideband on it (was ganna wait until funds were in surplus, but gatta do whatchya gatta do)

and if anything my motor is running rich
idle- 14.7
normal driving- 14
1-3lbs of boost- 12-13
5-6lbs of boost- usually 11
6.5+lbs of boost- needle sits at 10 with the rich warning light blinking (less that 10:1?)

*all these numbers fluctuate +/- .5

a good forum to join is 22rte-trucks and also look up jeff mosk's site, not the most info in the world, but better than nothing

 

And this is a fully stock RTE, or just an RE with a manifold and Turbo?

 

x1Billion... Seems that always ends up with something like, "Need new AFM"...

 

well if you have a wideband and mark the stock location of the teeth, i think it would be okay, but if you're guessing on how much to move it then chances are something is going to get screwed up

honestly, just get a wideband, i bought mine from glowshift for $152 shipped, cheapest i saw and its got a bosch lsu 4.9 sensor and it literally is idiot proof to install, from pulling out the drill and welder for the bung to test driving the truck was less than 2 hours

and with the wideband you know whats going on not guessing based on the plugs, like i said my plugs were white as can be and if anything im running on the rich side

 

hello I’m having the same issue with my 20 over rte truck same a rebuilt engine damn near everything new also have a lce turbo kit with a gt25r turbo my turbo is red hot on a regular drive down the road every one is saying it’s lean any way you fixed your issue I’m buying a wide band so I can get a reading just curious if you figured it out
