The chart shows a higher afr due to the fact that the dyno's afr wideband is connected to the exhaust venting system attached to my muffler that is obviously after my cat therefore showing a hight afr than what my aem afr wideband was showing me before cat.
As i stated earlier in the thread im using s52 21.5lbs/hr injectors
Also stated earlier that my fuel pump had failed on me a few days before that last dyno run and hasnt been holding the same fuel psi as before.. I had to make changes on tunerpro rt just to get 13~ afr on my wideband. Which is why i have on order a better fuel pump.
Gone but not forgotten
