i have a 04 monte carlo ls with the 3.4L engine and im looking to do some performance upgrades but i cant find anything for it. i went to my chevy dealer and the only thing he had for the engine is a drop-in k&n filter, i cant even get a cold air for it(i guess the model for the 3.8 wont work with my engine). ive also tried to find aftermarket superchargers, with no luck. ive read on here to not use the hypertech programmer, so now im at a loss. im a metal worker but i really dont want to go and custom make everything for this engine(intake, headers, exhaust,ect...). do you all know of any sites or companies that make products for this engine? any help would be greatly appreciated, thanks.
