I put together my own Methanol injection together from this website (http://www.turbomirage.com/water-alcohol-injection-installation-instructions.html). I am amazed how much this has brought the Buick alive! I have absolutely zero knock now and feel like I have added 50 horsepower! I should have done this sooner. It also amazes me how cheap and easy it was to install. I have around $150.00 in the whole thing. I am running approximately 18 pounds boost. I used to get around .7 KR at shift and at the top of third gear. This has been completely eliminated. I do have a few things I want to add like a few LED's to know when I am spraying. It took about 3 hours to install, but could have taken a lot less...I am just a detail oriented person I guess.
