Thanks appreciated.

Now the rest of the story..
Exhaust system:
Fullsac DX recored mufflers, 2.5" baffle2" baffle
It had 115tq at 1500, the red run.
Very few motor combinations, in my experience, will take full throttle in 6th gear at that low of rpm and not throw a big dip in the curve later to recover.
This is where credit goes to the combination with emphasis on pipe and cam. This was a very cool running motor as well with the low compression.

2.5 baffles? Holy Cow! 2.0 or even 2.25 baffles would improve the low end hit big time. Not that you need more. But if everybody is happy, better leave it alone!

Never argue with idiots. They will beat you with experience.

Got the straight scoop from the owner 2" baffles packed.  Fits the curve now. Sorry for the confusion.

I have the TM625 cams now, and this shows me what I am missing on the bottom.
When those 625 hit it's on, but too soft down low.

Since this thread was comparing the TM625 to the TTS150 I thought I would share my dyno

Unfortunately it is not fair to get too deep into comparing cam grinds or manufacturers when there are so many other contributing factors. The TR625 was developed when the 95" was popular and is a torque grind when it has the mating parts to go there including and especially the pipe and the needed compression. The close LSA and lots of overlap can cause the build to be somewhat pipe sensitive. When the heads are working well and properly sized for the demand I prefer a cam with wider LSA but still with an advanced intake LC in the 100 neighborhood. Despite talking about cams I am careful to not take the cam out of the context of the whole build.
