halfway up the dune (on the second and third try) my 4wd was making noises. a popping noise and then a weird metal clanging noise. so i let off the gas on both occasions and wasnt able to make it up. jb thinks there is air in my vacuum line.

Hey, Noah, Look at the connector that is just before the transfer case shift motor. Have you had a lot of rain recently? Mine was't waterproofed at all and would act up if wet, sometimes partly engaging, sometimes not going in or out. But, it does sound like an IWE related thing.

It is different than the HP and TQ that are measured on a engine Dyno since you are taking the drive train into consideration.

Sorry, yeah. I meant what is it for a stock truck, those two numbers?

Well this was done on a Mustang Dyno which does read lower than a Dynojet. But stock numbers from a dyno jet are from 320 to 330 RWHP normally and about 350 +/- RWTQ.

But those are DynoJet numbers, the way a Mustang Dyno works makes it almost impossible to compare numbers between diffrent dyno's even between the same mustang dyno brand dyno's.

He did pull up a graph of a Raptor with CAI, Tune and Cat back to compare to mine and you could see a large increase thru the powerband from the Headers.

Next dyno day in the area at a DynoJet facility I will try and get some Dynojet numbers
