For some reason I let my friends talking into drag racing my 2004 Dodge Hemi 4x4. After a couple of trips a guy at work wonted to race me. He has a Nissan Titan 2x4. On the way to the track I knew I would need some help against such a lighter truck. So I went buy the local dealer and seen the Lucas Octane Booster, For race use only... I was sceptable but tried it. Normaly my truck only ran 10.4 second runs (1/8th) mile. But after vthe fuel treatment I actually beat the Titan w/ a 10.005. What a great product. Thanks Lucas...
