MAF Question

Going to be running a Vortech A-Trim with a 2.95" pulley and power pipe.

My current setup is a 306, Edelbrock Heads, X-Cam, Typhoon Intakes.

Going to buy 42# injectors.

My question is ...... should I send my 75mm MAF out to be recalibrated for the 42# injectors, or should I buy the 90mm Ford racing MAF with the injectors as a package?

Not sure the 75mm MAF will be big enough.

Second Question...is anyone running this MAF and is the plugin the same?

Thanks
