long story short...customer brought us a Truck to fix a sugring issue and for us to put a different pulley on it to make more boost ....
turns out its an issue caused at the MAF by some airflow reversion with his blowoff valve
Failling the MAF and putting it in SD seems to have fixed the surging issue(and smoothed out the throttle response quite a bit as well I might add...)
so we put the thing in SD....the issue goes away...(MAF failed in the tune)
but we go to do a basic tune on it...to make sure WOT AFR looks good, make a pull....
and no matter what I do to the VE coefficients, above 4400, AFR goes up....
starts to rise and by 5800 its up to 17.5:1...obviously that is no good...
so I proceed to use the EQ-VE software to add to the VE table....
I've thrown an extra 50% fuel to it and it seems to make ZERO difference...
what am I missing
MAP sensor only shows 118-119 kpa.... so its not making any serious boost..LOL..so I'm not too worried just yet
but I need to get it to add fuel up top before I change the pulley out and start beating on it.
is there some other table besides the coefficients I need to make changes to on the 2014+ ECU's?
