Are my dyno numbers a little low?
Hey Patrick G and vendors where is my torque? The car is a 2000 M6. It is stock bottom end, clutch, rear, and injectors.
The mods.
1. TEA stg 2 ls6 heads milled to 61cc
2. ported fast 90.
3. 226/228 114LSA +4
4. SLP intake.
5. Powerbond underdrive pulley.
6. QTP 1 3/4 headers
7. QTP off road y
8. Magnaflow exhaust
The car not only to me has low numbers but i personally feel it is sluggish especially below 3500 rpms. Here is the graph. I am up for any suggestions as to what can be the problem or just someone to tell me that the numbers look great.
To the vendors that i bought these parts from. this is by no means any attack on you. I had nothing but great service and help with my car from everyone. I just need some more opinions.

why did you stop pulling at 6100? That shouldn't peak until about 6300..
and it could be a stingier dyno, they aren't standardized or regulated to read the same numbers
I also can't see your A/F.. and your tune could be a little off..

I am not sure why they stopped pulling at 6100. The horsepower really wasnt what disappointed me it was the torque that did.
As far as the a/f ratio the original graph was 13.0 across the board

Some tuners/sponsors may come in here and tell you to have the tune richened up a bit in the midrange to increase torque and you'll probably see a bit of hp free up as well. These things dont like to see a really lean curve to make their power.

Not the strongest h/c car out there, but no slouch either. You are running a pretty mild cam. What is your compression? Post the a/f ratio to help get some insight.

Stock fuel cutoff on 2000's is 6200
That's from my A4 tune but it accounts for all gears 1-6 and P/N in the .bin
Could explain sluggishness too I suppose.

Looking at the curve i think either valvetrain or tune up issues. Knock retard,to lean , to rich. The curve shape is aweful.
