So I was browsing on Craigslist looking at some gtp for ****s and gigs. I came across a somewhat modded one that had a meth/water injection kit. I was wondering how good are those for our cars. I also own a 86 turbo Buick and I know in that community meth injection is used a lot. But I haven't heard of it it In wbody till now. Here's the brand the car on CL had http://www.alcohol-injection.com/en/156-grand-prix-gtp
