I just went out and did a few pulls with my dynojet wideband. I logged my MAFvoltage and it was at 4.8 on one pull and about the same on the second pull. Does this mean that I need to install a MAFxtender? The temperature was around 80 and humidity was almost 100%. Am I going to peg the MAF in cooler temps?

You are ok until it pegs at 5V. mine is at 4.9 i beleive. The workable range of the sensor is 0V - 5V.
what mods do you have?

Magnaflow x-pipe and catback

That's all for performace mods.

I'm not sure, I haven't had it on a dyno yet. I will be doing that in about two weeks or so. I'm guessing around 480rwhp-500rwhp.

Yeah...5.0V is pegged.

You did some WOT pulls while untuned? Be careful...

been through this just recently, even have a bunch of threads where I posted some questions.

but yeah 5 is pegged, for the rest of you dont assume its pegged or not pegged, I have 600rwhp and even I only hit 4.8 volts all the way to red, effectively NOT pegging the MAF. I put a MAF.ia anyway just because I didnt want to play too close to the line.

lesson, always data log your stuff.
