School me on wastegates!

I found my truck dyno'd better with the top gate opening at 20 and wide open 35 to the bottom turbo, peak boost on # 2 only 58 psi. If I closed the top gate I see 74 psi but less power due to restricting of the exaust flow. The idea is flow as much air as possible, get the top gate open and work the bottom turbo harder. Just my $0.02.

Well put!!!:clap:
 
I have question. Did you buy the kit or was the top turbo bought and then the kit. I believe they use diff. WG for the twins setups. I know HTT wanted me to send them the top turbo to replace the WG. Just a thought.

Was this directed at me? If so, It was custom built by Brad Ponci.
 
You need a bit more out of the S400. Something around 33-34 for your total boost. It seems like they like a max of 38-40 but your total boost needs to be higher for that.
