I was about to order some 42# injectors for my s/c kit and was just wondering if these would work...It says "These injectors work best with air meters with revised calibrations. Not recommended for stock air meters". any input? are these good to go?

 

With 42 lb injectors your stock Mass Air will most likely be maxed out. You will need to get a larger mass air or get a MAFia which extends the capability of your stock one. Your tuner will calibrate the Mass Air once the s/c is installed and you have it on the dyno.

I chose to use the MAFia. Sounds like the injectors are fine. What ones are you getting. Just get the FRPP ones if you can. They are made by Bosch.

 

the maf xfer function and injector slope are programmable. It is NOT a problem for anyone that knows what they're doing while tuning. that said, you really should be moving up to either a SCT 2400 or a 90mm Lightning MAF, both of which require some tinkering on the tune but nothing huge or difficult. There's no reason to run that close to maxed out on your stocker. NA cars have no reason to ever replace the MAF but blower cars are another story altogether.

 

theres a guy here in germany selling 42# injectors and MAF pretty cheap. 300 bucks everything. shipping is not a problem since we have AP0.
