Default adjustable Map Sensor

I got a buddy that can get Adjustable Map Sensors for $50.. Does any one know if the adjustable map sensor WILL provide more fuel delivery hence more power?
I researched a bit and didnt see much on "adjustable" map sensors.

Let me know if i should do and if there are people here interested in like?

Won't do much on a stock engine, it's more for a stroked engine with other performance mods.

with a MAP adjuster you can fine tune the amount of fuel your engines getting by fooling the computer. i doubt that it would do much on a stock engine. id free up the e intake and exhaust before you add a map adjuster.

for 50 bucks I'm totally interested in one though

Adjustable MAP and Adjustable fuel regulator = more power..

but yeah.. its mostly for stroked engines.. but if you add mustang 24lb injectors it should provide better spray

get about a 15hp increase maybe worth it

A lot of good more fuel will do if you can't get more air in and out of the engine too.

I stroked my engine and tried using the adjustable MAP sensor. I ended up getting rid of mine because the ECU tries to compensate too much for the variable... not worh spending the money on and you chance leaning it out or enriching way too much with that thing. Stick with stock unless you stroke it out. Otherwise - save some money and re-gear for power.

I've tried one on my 4.0 cuz I got it for free. Set it up the way you're supposed to. I took it off.

And, if you want a way to adjust your MAP sensor, get one for $25 from www.strokedjeep.com.
