    hey guys I just got a URD MAF sensor calibrator and I'm debating on whether I should install it myself. I don't want to risk messing my ECU up if i do it worng. Has anyone done their own or seen a write-up on it?

    I know one thing... it takes away your low end torque. my truck usta spin the tires pretty easily before i put it on. but now seems like i lost power! cause i never drive my truck at wot. it puts all the power up top in the rev range were i never see it!

    ya they have a harness so you dont have to worry about soldering...anyone with a 2.7 have this done? that would be nice to see if anyone experienced any gains with the 4 banger...

    also dyno sheets in general are always nice

    is that because low rpm's run in a closed loop and then higher rpm's run in an open loop allowing for tunability?

    when you tuned the maf did you tune more for torque (low end) or more for hp (high end). i would assume with this you should be able to adjust the a/f ratio in all rpm ranges to achieve the results you want.

    doesnt running on a leaner ratio provide better torque and richer at higher revs more hp? maybe try playing around with it and seeing what happens to throttle response when you change things up a little bit!

    should be like 15 hp or close to that but its all up top so i dont even notice it. all i notice is the lack of bottom end i have now compared to what i had with the cai and catback
