Your numbers are spot on for these mods.

This package generally makes 670-680 RWHP through the automatic = 850 crank HP. Our last M6 build made 734 and 707 WTQ.

Without us doing the install/tuning it's hard to say what's going on. Whether it's the dyno, tuner or installer, It's hard to say for sure without having the car here, or at least looking at a data log.

Thanks everyone for the responses. And as I said before, Tyler and JDP have been more than helpful. But as he said, only so much they can do without seeing car and that's not possible with me in Alabama. That's why I put up this post hoping to get insight that might help me figure some things out. Thanks again.

If I were you, the very next thing I would do is set up another dyno test at a different dyno. You need to know for sure if the first one was 100% correct.

^^^ this. Also I assume the shop and tuner you are using is reputable?

Agreed, the tuner is often The most important piece of the puzzle. Revo, I noticed the new ZL 850 package now has a few more things than it used to. Did you add any extras or did you just have the base 850 kit?

I have 700RWHP with similar mods so he's light at only 580rwhp.

650-680 is where he should be with an automatic

I'd test on another dyno to confirm, and go from there

Ray,

Have your tuner send us the tune file to jordan@jdpmotorsports.com so we can take a look and make suggestions.

Hmmm. Good question. What was added?

[blk13]

I have similiar mods making close to 700rwhp so you definitely have low numbers.
