Hi Gang, Has anyone ever used products from “CFM-Technologies” on there TBI equipped Blazers? (http://www.cfm-tech.com/catalog/gm_tbi_performance_parts___accessories_126905_products.htm) CFM-Tech claims that there products will Give You More Horsepower and MPG. I’ve read that TBI spacers aren’t worth the money and really don’t help much. I’m looking for honest opinions from people who have bought and installed CFM-Tech products on there TBI Blazers. I have a 90 K5 Blazer and with gas prices rising here in So. Cal I’m looking for stuff that might help my power and MPG. I find the write up on the fuel regulator rather interesting, any thoughts? Dan..
