Took the car out for another long drive this weekend. Have you ever heard of adding 2 tie wraps and getting about 100 horsepower more!
Neither did I!!!! But that is exactly what happened!!!
I can finally say that this car is scary fast. I was a bit disappointed when I first got the car running with the power level. It was faster than before but just wasn't as fast as I thought it should be. I haven't installed the new exhaust and the current exhaust is VERY restrictive so I though that might be the issue but it still seemed like it should be faster.
So last weekend I installed a boost gauge and low and behold, I was only getting 4.5 pounds of boost MAX!!!
The LS9 has a blower bypass butterfly valve that when open, it creates a passage around the blower. The stock GM Engine Management Computer controls the valve. I forgot all about that valve. The Engine Management Computer I am using doesn't have this specialized control.
So yesterday I took 2 tie wraps and forces the valve off, all the time, off!!!
OMG, what a difference!!! This thing runs like a bat out of hell. I couldn't be happier. And I am still running the restrictive exhaust. I can't wait to see how it feels with a free flowing exhaust.
And I am getting north of 20 MPG!!!!
