i know two friends that have them and both of them are really happy with them. but i have also heard from other people that they would never buy one. so like it was said before you got a 50/50 chance of gettin a good one.
alot of times i run an unleaded 100 octane gas mainly when im heading to the track or want to clean it out. so what your saying here is that im actually hindering my performance by running this stuff?
