[QUOTE="wimpykid, post: 631370, member: 3559"] Gonna give an update on the FiTech unit after it has seen a few full throttle uphill assaults mixed in with some trail riding. I have had one other issue of not firing once offloaded from trailer, washed, and trying to pull back into garage. [color=red]But, I think it have figured this out.[/color] I am running an RPM Air-Gap intake and when I wash my rig, no hood, water gets into the depression of the intake. This shouldn't be a problem, except the plug from the ECM that is supposed to plug into the distributor wire (my distributor plugs into the MSD box) was laying in this bit of water. Dried the water out of the plug and it fired no problem. Solution to the problem is I have weather proofed the plug. This wasn't the original problem, but I believe it was the problem back in June when it wouldn't fire after being washed. I had driven in the rain before all this, but when your on a step hill, moving rapidly, and the engine is hot, water doesn't sit in the intake depression. The FiTech does good, but I need to take it to get it tuned, as I am in no way good enough to get my A/F ratio correct. It is running extremely rich, which could be because I am running shorty headers with no mufflers and only a short piece of pipe. I'm in the process of installing long tube headers and bullet mufflers with a short piece of pipe and I'm thinking this should allow the O2 sensor to get a more accurate reading. I'm still going to get it tuned in hopes of cleaning up the richness of the exhaust fumes and tweaking any extra HP out of my lil SBF. I have contacted FiTech to give them a heads up on an issue that wasn't due to their unit, but might affect others with the RPM Air-Gap intake. [/QUOTE]
