So, I just got the TW chip, haven't had a chance to really play, always pulling a trailer. Today while out, w/ the girlfriend, (who just found out I spent that much $$) I was telling her the Extreme tune is very quick compared to the Diablo chip I had. Well.... loong story short, she wanted to see smoke, and it just happens we are first at a light. This dumba$$ pulls up beside me all ****y and flicks a cig. in my bed. (its a 4 door explorer) So I told her you wanna see what these 7400lb trucks can do.... she was all about it!! So... did the usual...4wd/spooled to 4psi, this guy wanted to play. Light turned green and by the time I got a chance to look, at least 4 lenths, and a nice cloud he's driving thru! I let him catch up, he tell me I'm #1(LOL) and I blow some more smoke on him and the whole time the girlfriend loved it!!!! Thats the best part.....I see more mods in the 6mo. Just too funny how much fun she had, I think she liked it more than I did!
