Hello Ford fans,
I know this topic has been around for ages, but I am close to purchasing a mew MAF sensor and I cannot for the life of me decide between these two.
The Granatelli motor sport (Pro-M) item GRN-75955024-00, or,
The Vortech (C&L) item 8A301-023 (with 24# sample tube).
The GMS sensor do have electronics specifically designed for the injectors used, which is good for engine load and less hit and miss with calibration, but they don’t look as stock as the Vortech ones and they cost half as much again.
The Vortech sensors don’t have their own electronics and there calibration depends on the size of the sample tube, and have a tendency to run rich, but they do look stock like the EBGT/Sprint MAFs.
I will be fitting an Explorer intake, and I am going to fit the old H.O. engine cover over it for the stock look.
I will also be using a Kirban adjustable fuel pressure regulator and will get it tuned on a dyno.
I will be using some Bosch injectors (out of a magna) that are about 23.9lbs, which may offset the inherent rich condition the Vortech sensors have, but may throw the GMS calibration out a little.
What do you guys think? Is the GMS product worth the extra bucks?
I’ve been in two minds for ages and have to decide soon.
I might start a poll to make things easier.
Cheers to all who read this and respond.
