Default Maft or maf causing misfires

Ok here it is Ever since I got these #42lb injectors its missing sometime(was alot worse). I ported the maft and it got worse. I then richen it up and it stoped alittle but ist still there. I have to atap I think. But it throws a code and you can feel the hole engine change so it must be in some kind of reduced power mod or something. I'm thinking maybe a maf code low or high code or malfuntion. time to put the comp on the charger

What are your LTRIMs? 42lbs is a lot of injector to compensate for with just a MAFT.

So, how are you correcting for the 42lber's? Ported metter + maxed out lean maft?

If you still have an 4L60E tranny drop me an email.
