pulls like a beast and am very pleased with the build. doesn't run too hot and handles great. tons of power.

still having a bit of a rough idle on warm-up but once it's at temp is fine. just need to tweak TTS a bit.

also trying to find an annoying chirp that started after build (it's not the rubber exhaust hanger). i don't think it's a lifter...well i hope it's not a lifter. when you're back at the pipe it sounds like it's coming from inside the pipe. when you're standing next to the engine it sounds like it is coming from underneath the engine in the middle. no head leaks, intake leaks, or exhaust leaks. it mostly goes away once the engine heats up. any ideas?

Nice looking Dyno. Did Geoff do the install as well? Haven't seen him in a while. Looks like a fun ride.

I have the 580 cams in my 2012 with TTS and runs great. It does run a little rough when first started, but after 1-2 minutes. it's fine

no, geoff just tuned it for me. interesting to hear that others have a little rough warmup on these cams as well. not a huge deal to me as they are bad-ass cams! i'm sure once i run some datamaster logs i can smooth it out.

A buddy of mine had a similar noise, same location and got better when the engine was hot.

It was an O2 sensor that had come loose. You might want to at least check them.

Also,

I have the 580 cams as well and still not dynoed yet. Went to the Grand Canyon a month ago and it ran like crap at elevation. Spit, sputter, cough....lol you get the picture. Back here at sea level, just a little sputtering when cold is all.
