I made a return trip to TPIS yesterday to see what kind of numbers I could get with my fuel enrichment turned ON.   I was hoping for 450 horse, but ended up a little shy with 437 hp/ 380 tq.  We did 4 runs in 15 minutes, I think with a cool motor  I would be there.  All in all I'm pretty happy, it's got a nice flat torque curve and if drive train loss is 15-20% that should put the motor around 530.

Those are some nice numbers. How is the oil leak concern with the new cap?

 When we ran it last time I had 403hp at 5700 when we stopped the test.  I was a little surprised I only picked up 6 hp as lean as it was running.  We did find that even with my fuel enrichment turned on I was still pretty lean.  After we got it dialed in it only dips rich in one spot. 

 Re-routing the PCV and the new oil cap have made a difference.  The Dyno pull hold RPMS higher than I would typically and from what I can see there was no oil being pushed out the back.

Looks like some nice numbers without having to get the rpm too high.

Great numbers and good news on both the tune and the oil control concerns. The confidence Dyno tuning delivers is worth the price.
