I put in a dyno tune kit on a new cobalt SS 2.4L auto came as a N/A car.
thats what got me started. dyno tune has a pretty good product if you ask me. He had the 4cyl stage1 kit, he added the adjustable bottle heater, guage, purge kit. he still is waiting for the window switch and some sort of box for us to mount all teh switches and shrink wrap for the wiring in the passenger cabin (he doesnt wanna cut holes in his new car)
its a nice a$$ kit!
now i have the itch again. if i did get it again, i'd be sporting 2 15lb bottles and a direct port kit with a progressive 125 shot starting a 50% ramping up to 100% in 2 seconds. ugh i gotta stop myself. thank god i don't have money for it right now.
