I would expect that it would be even more beneficial to you since your motor can move more air and fuel than us stock cam guys. I would be interested to see if there is any benefit to the larger ported tb in conjunction with the z1 maf. Do you have any pics of your ported lower plenum (1cockyz)?

 

Just wondering if you ever thought about putting an M45 or FX45 throttle body onto our cars as oppose to porting the stock one out. not sure if it even fits but just wondering, since the price is more or less the same and the size will be larger on the 4.5 engine one.

 

tb and maf same size on the v8. the titan even has the same size maf. There is a pic of my cleaned up lower on my build thread I think.

 

That's right i keep thinking it's the same size as the q45.
