[QUOTE="brownsvo, post: 16424664, member: 152050"] So I have an 04 cobra, pullied w/ JLT Ram air, and catless exhaust. I've been driving it like this for a year or more. Now, fast forward to today and I've installed a canned tune from Bama for 91 Octane, along with an Innovate Wideband. What worries me is that driving around normally I'm anywhere from 17-22 in the red. I thought it was my weld job, and that I had a hole somewhere so I replaced exhaust gaskets, rewelded the bung, and checked for leaks using a light. It looks good. My AFR does drop while in boost, but I haven't hooked up a data cable to it to log. Frankly now that I have a giant blinking gauge at eye level I haven't beat on it like I have in the past. I have zero trouble codes, and replaced the vacuum T with new lines behind the supercharger. I have also provided a small window of a tiny 4th gear pull to see if it could be something other than too much air, and possibly fuel related? I haven't investigated what is normal for the fuel ranges quite yet. Which is why I'm asking for someone more experienced with these things to please take a quick look. -Thank you! [/QUOTE]
