I have wondering how to use all the potential of the setup I have. I have the truck gated at 58psi (guage goes to 60) but it still smokes on the top end like my single setup did. My new guages will be here very soon and I was wondering if I should throw some more boost at it to clear things up. Could I get more power out of the truck or should I go to a dyno to figure things out?

Thanks

 

instead of using shims...... get an adjustable wastegate..... or cut the stockers wastegate up and tac it to the twins secondary wastegate.... much easyer to adjust boost this way.......
