Dynamic Test Sytems @ XS Engineering - 155hp/181lb-ft
Maha @ AMS - 105hp/120lb-ft
Dyno Dynamics @ Vishnu - 102hp/142lb-ft
Dynojet @ HKS - 152hp/193lb-ft
Dynojet @ K&N - 156hp/196lb-ft

Take from that what you will, I copied that right off the graph. I was a Ranger with a 4.0L, and they used 2wd and 4wd dynos.

I read that same article and I from what I've seen. I agree. The bottom line is whichever place you go. Your car is still the same.

Mine dyno out at 248 on a Dyno Dynamics while a friend did his on a Dynojet and got 275. The only mod difference is he has an Apexi intake while I took my HKS RS intake out and he's running the P2 while I'm running the XFlash.

I think the lesson is to always use the same dyno, or at least get a baseline each time. I personally was shocked at the range of differences.

Exactly, which dyno you use is up to you but if you want to tune, use the same one all the time. Even the same dyno will read differently depending on weather, but at least it's the same dyno. Don't rely too much on what the numbers are for baseline. When you start adding mods, you can then accurately determine how much WHP you gained per mod.
