If ya listen close the tranny or tqconverter locks up at the same time, maybe a lock up switch on that side of the dash and he hit the turn signal lever? Looks to me it's still smookn pretty good...id say no NOS!
Im sure it is doing something. It doesent really seem like nitrous to me though because it doesent sound any different. The TC locked right when he flashed the lights, but i dont know why youd have the light switch locking the TC. lol
i know he never was close to us he beat me up there but i did have some problems but he was knocking on chars back door he did the same at westmoreland there is something strange about the lights
