obz at WOT at 10lbs. I read rich. I did not have laptop so i could not get the wideband numbers. I use a nice set of lights one for each bank of engine. They have a nice safety margin in them as they read the color in general ahead of the actual AF condition so that if it is getting to lean You can at a glance under WOT see it like You would be glancing at any guage. They are run off factory AF sensor. I will be using the wideband for serious tuning shortly. I can with on board computer put the actual wideband numbers up on the dash screen with HPTUNERS software but, i have to look down (bad) and to the right (bad) to much so thus the 4 light system one set for each bank let's me see looking straight ahead.

I'm running the stock TB at this time. Not sure where i will go with that yet.

The tune was actual the kit tune which strangely the computer was able to get a good enough reading off the MAF and mix enough fuel for the first tune and launch in an awesome run. Then it did not actually act like it went to limp mode because it would still run real good and all gauges looked Ok as far as safe and not hurting anything. It was just wierd as I could pull the tune and put it back in and then another great launch.

We have put the kit pulley back on it for a good while and with headers all the add ons it runs good enough if i just were not into making it go and continue pushing it the mall queen runs really good with kit tune etc. at 6lbs. of boost that with an HPTUNERS tune at 6lbs. it would be a monster. I like to see what kind of beast i can let loose out of "The Beastly Beauty"

Hey Gay bob stop reading my post your arse. If you were not such a prick you would have something better to do. Go sit on something with AIDS and spin!

Taz and Obz thanks for all your help. I got my truck back and the shop said that the oxygen sensor had come loose, causing the check engine light to come on. Also, they had to change some programming in order for the volant maf to work proper. I drove it about an hour today to the country and it never varied much below or over 14.5 on the af gauge. I know that my gauge reads lean to the right rich to the left. My tuner told me that variance is normal though. On the way back tonight I averaged 14.5 but under throttle the number usually dipped some and sometimes when I backed off the gauge would read up to 16 but never stayed for more than 3 secs and dipped instantly when I gave the engine some throttle. The truck ran great the entire time and my check engine light did not come back on. Am I still in dangerous territory? Am I being paranoid? Dose the problem sound solved?

Also sitting in idle it almost always at 14.6. But my gauge is always going back and forth between up and down usually rich for the first few secs after boost as it speeds up and ramdomly will seem to peg 16 but almost always under little throttle or coasting at speed. Cobalt makes the af gauge. Again, the truck seems to run just fine the whole time all this stuff is happening and no more check engine light???? Also it always only reads lean under vaccum not boost. The saga continues...

The only time the af guage is of real importance is at WOT. The rest of the time I would not worry about it much.

I run a light system and I have a switch in line to cut power as the lights run up and down blue to red under normal driving. So unless i know I'm going to be in a WOT run I have them turned off. Boost gauge and fuel pressure gauges stay on.

Awesome I'm glad your on line! So why is there such variance, is it just the gauges showing compensation for vaccum vs. boost under normal driving conditions? Another weird thing is that my gaughe is wide band and red/lean is on the right and rich/yellow is on the left. It also gives the ratio 14.6 etc. Most of the cobalt gauges i've seen are the exact opposite. I just hope I finally get to start enjoying my charger instead of waiting for the engine to grenade.

You got the idea. Plus it is just af jumping around at cruise or slow down so the vacuum sort of mirrors that.
