[QUOTE="96vert, post: 181183, member: 2923"] Congratulations on getting the Vortech - I'm sure you're having fun... First, I have to recommend that you get a dyno-tune before you run it too hard for too long. My stock vortech chip kept way too much timing in it up top, but also made it run WAY rich (it went off the graph, and the bottom of the graph was 10 air/fuel) After the dyno tune, I don't have any more black smoke coming out of my tailpipes, I have more torque, and more peace of mind knowing that I'm not blowing my engine up when I get on it. according to your description, I think that you are either experiencing spark blow-out or you are getting too much gas when the FMU hits and raises your fuel pressure. If it is a gas problem, a custom dyno-tune will fix it. For the spark blow-out: First, I'd ask the installer if he narrowed the plug gap to the recommended .035. (incidentally, even if he did that, you want to ask him if he went with the lower heat range copper plugs - that's what you want on a blown car - I use Autolite 103's, others use NGK's but make sure they are copper, one heat range colder than stock, and gapped down.) Next, check your plug wires. If you still have the stock ones, that will contribute to your spark blow-out. If those two things check out ok, then I'd check your coil packs, but I doubt that is the problem. good luck and let us know how it comes out. E-mail me with further quesitons. (should be in my profile, but it is on my site as well) [/QUOTE]
