hi everyone. I purchase a set of 42 lb lucas injectors. and purchase a pro-m 75mm , but is calibrated for 42 injectors, i dont read its for a 302 supercharged. I try to install , with the stock injectors and the check engine light turn on. I read in a forum the t-bird doesnt work with 42 config.V8 mafs I dont install the inyectors yet, but is a loose of time? or is posible the mafs works fine? PLEASE HELP ME!!! i need a new one? What configuration is ok? HHHHHHHHHEEEEEEELLLLLLPPPPPPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!:mad: :confused: my car is a 93 t-bird sc
 
You can't run a MAF set up for larger injectors unless you actually install the injectors. That's your first problem.

The second problem is that you need a different MAF to run those injectors. Sell the MAF and get the right one.

Thanks Dave, and what is the right calibration of Pro-M to run in my SC?
 
The correct calibration depends on what injectors you are running. Stock injectors is Cobra24 and 42's is Cobra34

ok thanks, but if i cant find the pro-m, just buy a c&l 76mm and a sample tube for 42?? is posible a 80mm with the same 42 sample tube? which better?
 
For 42lb injectors the biggest MAF you need is 75/76MM. A C&L will work fine if you can't find a Pro M. I have new ones if you don't find one used. Email me if interested.
 
Dave,
I have two C&L 80 mm for two cars both running late rectangular, all bolt ons, etc. Neither have electronics so I am assuming that the stock is retained.

Both will run 42's for now so what is correct tube color purple?

I also have a 76 MM Pro-M but it is calibrated for 36's and came with electronics.
