I was wondering if you have to get a new tune when you port the blower or is the enough adjustment in the predator to make the a/f ok. I was wondering how much it changes your a/f. Someone let me know. Thanks
Question about ported blower tunes?

The only safe way to answer that question is to get some A/F ratio figures...either on the dyno or with an onboard wideband O2 meter. Don't guess or take somebody's word on this one. Have it checked.
The norm is that you WILL need a new tune when you port your blower. Expect your A/F to be a bit leaner after. Bottom line. As Larry stated above, get it it checked after the porting and get a retune if necessary.
it depends how the car is modded when you do the ported Eaton. We always retune after a ported Eaton install is done here.
