I think you might top out the injectors first.... not sure though! The MAF is good for ~280whp. I wouldn't run more than 10 psi on 91 pump anyways, assuming you're 9.5 CR. I have my high boost set at 12psi on 93 octane. Could probably run more, but i like reliability
The maf will max out before the injectors. The injectors should be good for 320whp or so and the maf will max around 300whp. Best thing to do is to get the car on a wideband and Techtom so you can see what your hitting and at what psi.
This is from Andreas...
370cc injs at 4 bar = about 420cc injs
Going for 3 bar to 4 bar make the injs between 8-10% larger
370cc injs at 3 bar = about 250-260 WHP
370cc injs at 4 bar = about 280-290 WHP
250-260WHP is about 10% smaller than 280-290WHP
