eigenvector

I am running a 85 mm Maf right right with 42 lb injectors. I pulled 21% primary and my air to fuel ratio is around 11.6 at redline. Im running 22 psi
and my max MAF values are 270 g/s.

This setup is working however when I hook up my Water/meth injection Its going to richen me out. And I have to lean the AFR to 12.5 (says Boost Cooler).

Now my problem I can only pull 4% more via lemmi so should I get a bigger 88mm MAF ? If get a bigger MAF will I still have at least 260 g/s ? If i turn the boost up to 24 psi ? Or should I Make an open air intake, to try to lean it out that way ?
TIA

Need bigger injectors.

? If I'm running rich why do i need bigger injectors.. my duty cycle is 90%

You are correct. Maybe you should run open intake to lean it out some?

How about lowering fuel pressure a wee bit?

2nd, get an AFPR and play with your fuel pressure to get your desired afr.

Hey bud, how are you? how have you been! are you coming to LA soon?

right now....it's pretty important that I finish this stuff up, or I'd be stabbing my company in the back pretty hard.

The car is running strong....finally got an RS4 airbox to complete my intake....this with the afpr and avcr fixed all my LTFT issues, and the car is finally quick as I expected it would be with this h/w setup.

Just pulled a 3.0 FATS time last night....thank god for 50F weather .

nice! very nice! yeah temp does play a big factor as well as fuel too!
