While researching power adders I've read several opinions on the ability of stock fuel rails to deliver enough fuel.

Some say that cylinders 7 + 8 can run lean at full boost.

Any thoughts on this?

Anyone upgrade their rails because of this concern?

I was making 510 hp and about550ftlb of torque at the motor....430 at the wheels on the dyno at 5200 rpm with 42lb injectors t-rex and 255 in tank stock rails both feed and return.. at about 10 lbs of boost...at 11 to 1 air fuel ratio.....also had an afm pms computer...no fmu...

Thanks! That's very close to my goal and the place I will use for the dyno tune was not specific in this respect.

I plan on 36lb injectors as the setup I bought comes with a MAF that is already setup for them.

I'm rapidly reaching the limit budget wise. Nice to know this can be a an upgrade that can be bought at a later date.
