at idel is goes from 14.2 to around 15.6
at normal driving 14.1 to 16.2 is this right/?

 

about the same what mine does... mut while driving i rarely hit 16.0 AFR..

 

it hardly hits it but that was the highest i saw it so its working fine then

 

That sounds normal but, to make sure, floor it and see if it stabilizes between 10 & 11:1

 

ya it goes from 10 to like 11.5 i think it was

 

Thats normal

 

Install went good did it?

 

had wleded the bung in and had it all geared up in ten min

 

All vehicals that run off of gasoline (doesnt matter what you drive) are programed to run at 14.7. The computer will make hundreds of adjustments every second to maintain that number. So it will give a little fuel or take some way, hence why it goes back and forth. When you go WOT it should be around 11.0 - 11.5. My truck does the same thing, it actualy goes to 12.0 - 12.5.
