i recently just got the cobalt and man do i love it. ive had it for about a month now and ive had a few good kills. (honda s2000, 350z, eclipse gt) but i raced a srt-4 the other week and he pulled me about half a car. he sad he was stock but i knew better. not bad for my car being bone stock. well i decided that i needed cheap and easy hp so my buddy refered me to nitrous. ive never played with nitrous before but i figured what the hell ill give it a shot. i bought my kit off of ebay and got everything hooked up and the system looks really good. but when i drive down the road and i spray it nothing happens. i cant feel a power gain the rpms and staying at a steady rate (i.e. stock) but i know its spraying cause ive had to refill my bottle now about 3 times. anyone else ever have this problem. any suggestions would be greatly appreciated thanks.
