Haven't been online for a bit, as for boast I am running about 7lbs with no problem with no detentions. At the end that is what really kills the engine. I am running 92 octane. The power is nice, but what I really like is the sound. The only thing to note is when the battery is unplugged, and the computer has to relearn, the transmission has trouble shifting for a couple of hours, so I usually take it easy, and if its having trouble shifting let go of the gas a little then then it shifts, usually I have to erase any error codes that come up. After it relearns the shifting is unbelievable smooth, almost don't know its shifting unless you give it. I think what kills the engine is the people that only know how to drive in 2 speeds, stop and go. Then the engines gives. But any performance engine if you drive like that constantly will break too.
