Dyno Day With Drunkmann Tuning

Seolhyun got her first Dyno ProTune on Sunday, December 20th, 2015. I was aiming for a torque range of 350-380ftlb but fell short due to some technical difficulties. In the end, she made 340hp, 340tq on stock longblock, stock turbo, with a slipping clutch and and a small boost leak. I have read many accounts of people having issues with the stock clutch slipping once it starts pushing additional power so I was ready to accept that as one of the technical difficulties. The boost leak however, was something I definitely did not expect to see, especially after putting so much crunch time and effort into the final preps before the tune. The boost curve was pretty smooth, other than few occasional dips below 20psi, but there was a huge power drop after about 5800rpm most likely linked to the leak. After getting protuned, most FA20DITs have a solid power curve all the way to the 6700rpm redline. https://youtu.be/eGDmOg4IIl0

I gave ETS a call today to see if they had any help to offer on tracking down the boost leak. Originally their FMIC kit didn't come with a charge pipe gasket (uses a 2-bolt flange) so their instructions were to form my own gasket using RTV Copper between the charge pipe and turbo. After talking with them today, they told me that they had finally got their first production batch of pre-made gaskets in and they would send me one free of charge since my kit had not originally came with one. What a relief! Although I'm not looking forward to taking apart the whole front end again to go in and rework the charge-pipe-to-turbo mating, I'm hopeful that this will solve my problem. From there I can test, datalog, and get my map back up to full power courtesy of Drunkmann Tuning.
