I have a 2001 (built Jan 2000) 3500 5 sp. I bought the truck used and it came with a BD box. I assume it is an early version without the boost fooler because it only has the ECM plug. Which boost fooler would be best to run with this setup? I want to upgrade to biiger injectors in about 6 months and want to increase my boost before then. Also, approx how much do these boost fooler's cost. Thanks
