I am just about ready to get the new combo on the street. I have 42 lb injectors, do I need my FMU? Also, I have a 255 in the tank, should I run an external? Any thoughts much appreciated. My combo is in my SIG. Thanks!

You will not need the FMU with 42lb injectors running under 10psi and then with a Dyno tune you will see if more fuel is needed when you exceed that power level.
I removed mine. I have 42's and a 255 in tank. When I got it tuned I was told I had plenty of fuel.
Great, Thanks!
I'm fixin to get some 42#rs and go for more boost , what would be a good MAF to get? or can my stock MAF be recalibrated?

Thanks Fellas. I just got a ProM for $229 shipped from a local shop. I was going to get mine re-calibrated but had a C&L which couldn't be re-calibrated. My ProM seems real smooth so far. I've put a few miles on her with the new 42's and it seems pefect, for once! I'll enjoy these moments because they are few and far between.
