[QUOTE="HPLouis, post: 16674562, member: 5445"] I was thinking of throwing a pulley on my car but I spoke to my tuner and he recommended against it because he said that I would need at boost a pump, at the very least. Now my tuner is conservative and I like that. I'm not racing for money and this is a weekend driver so he took all that into account when creating my tunes. For example, on my Terminator, I have 18 degrees of total timing on a 3.0 pulley with 93 octane while I've read of people having 21 degrees of timing on 15lbs or more of boost. Now, I've been checking out people's signatures and setups on forums, groups, etc. and I see a lot of people with 10-15% underdrives or 2.4 pulleys and they're on stock injectors and fuel pumps. Are these people running on the ragged edge? Can the stock fuel system handle a 2.4 pulley? Thanks [/QUOTE]
