No I still have the issue. I’ve started using the ECP Power button which seems to keep the revs in a better spot to avoid the problem. I still plan to have the injectors serviced soon, hopefully that’ll have an effect.
 
Mine didn’t even start doing this until six months after putting brand new OEM injectors on. Did you have the ECU serviced?
 
I did have the ECU serviced. That fixed some other issues with shifting and warning lights, but didn’t change the acceleration pulsing.
 
I’m suspicious that it’s the fuel pump itself and I very much want to put in a mechanical pump.
