I decided to install boomba valve today ahead of the new RRM ultimate ECU because I wanted to know which mod I was going to feel was doing what. If that makes since. I went for a short ride about 40 miles to run errands all at less than 4k without sport mode. When I hit the 80 mile mark I will put the boomba to the test. I did use about 1.5 foot of 3/8 fuel line by Gates to hook it up. I could not find any vacuum line that size. I am hoping that will not make any problems.
