High RPM sputter??
Tonight I heard what I believe was my first detonation...I revved it aty about 35 to pass someone and as the RPM's grew high I heard a "sputter" kinda sound....Could this be detonation? I recently just installed my 2.70 upper, SBTB, JLP ram air, and other mods...I have a chip but it isnt tuned for any pulleys, was that detonation I heard???
edit: It was more in the exhaust system than in the motor....just to clear that up!

Isn't it a bitch to pick out a noise over all that.
Between the Eaton Screaming Wind, and my Accu Fab Whistle,
I can't hear a got dam thing, but when my filter clogged at the
track, and I toasted 3 plugs, it started detonating and
there was no mistaken "something was wrong" ???
Sounded more like a gang of bandito's under my truck
with sledge hammers
OR SOMETHING ???
A toasted plug will give you a spudder too,
BE CAREFUL 400HPHD, I see your from Ohio, I got to assume
your having some serious temps too. But a 2.7 pulley shouldn't
be anything to worry about, many run it with no chip.
Did you set up the TB ???
It's real simple, if you didn't when you get a chance, check it.
Here's my "HOW TO" on it

Yes, they all need to be adjusted, even if you buy it with a TPS
already installed. I can tell you for a fact that's the correct info
in my "How To"
What it does when not adjusted correctly I truthfully DO NOT
know ??? But mine seemed fine when I put it on, and as my
link there showed, it was waaaaaaay out of wack.
But everyone say's you got to adjust it, so I did.
Maybe someone else will pop in with a better understanding
of what it would do if incorrectly adjusted ?
