Test Pipe Gains ~ 11whp/32wtq on VD
 

Just installed my UR TP, and did a quick pull at my usual spot. I was surprised that there was no difference in sound with the stock exhaust, but I'm happy it's still quiet and doesn't drone. Overall, I'm happy with the upgrade for the $$. Both runs were on E26 and at 5400' ASL, so the numbers are lower than they'd be at sea level, but the gains are still there:

No tune changes? If not then I'm surprised you're not overboosting.

I did reduce my WGDC's a bit in the mid-range to prevent overboost, and you can see my AFR's are a bit different. This was my previous best pull against my new best pull.

Can you post the log?

Sure, here you go..

Lol fwd

you at the border of needing a fuel pump

One of the benefits of high elevation is that we can do a few cheap boltons before needing a pump, but yes don't think I didn't see that 1585psi log point. A pump is on the list.
