I installed my LMS 4X tune last week and at first I was afraid to get on it because I thought something might break. That all changed when I pulled up to a red light next to a SRT8 Challenger, I know on paper he has the faster car but it all depends on the drivers launch skill..I smoked him off the line and shut her down at 60mph with him still behind me. We met up at the next light and he said WTF is in that?? I've come across many cars since then and have not lost up to 60 yet, Pontiac G-8, WRX, Mustangs, Camaros..etc..All the drivers have that smug "I'm going to smoke your Taurus's ass" look...until they are in my rearview mirror. If you don't have a tune..get it! I've recently had the transmission slip TSB done and a new PTU installed (the last one came apart) so I'm confident with my drive train. On a side note, every wheel bearing went bad last winter, but not all at the same time, every three weeks another would go until I had 4 new ones and all covered under the warranty.
I go to the 1/8th mile track tomorrow at Lancaster's cruise night for my first runs with the 4X tune. My best time with only a CAI, low tire pressure and as light as I could get was 8.95 for the 1/8th. I'll post my slips when I get them.
