Well, just to share with you guys, here's my dyno from TAG today. I got a peak HP of 187HP and peak TQ of 180lb.ft... that's up from 177HP/174TQ from last time. This is what changed:

Definitive Motorsports pulley installed
New spark plugs installed - copper

I also set my Harlan RPM switch to 5100RPM (which is why the HP/TQ do not dip after 5000RPM as you can see in the blue dyno line from last time).

The temperature conditions were about the same... not as much of a correction factor, yet the numbers are still quite a bit higher than last time... so at least I was able to get a comparative dyno.



I kept the test pipe off... and am running my old stock cat. I wonder if I plopped that back on, if I would get another 5HP or so, that I lost from last time. Here's the dyno from last time of stock cat vs test pipe:

 

you should set you VI at 5300 or 5400.
