I LOVED my VanAaken Stoopid box on the 250++ setting!! I know it's do-able with EFI Live but I've not had an EFI Live tune yet that had the rolling tire burnout like that Stoopid box did! If it didn't have the rev limiter in it that caused the alli to tie up shifts, I might even still have it. I definitely had more fun in my truck back then than I ever do these days. It was a solid 475rwhp setup & just ran stout.
I'm pretty sure I know a guy that still runs the bastard stack. If he doesn't now, he's only recently switched it. I also know one of, if not the first guy to run the triple stack. He dynoed 500rwhp in early 2004 with his 2003 reg cab long bed zf6 truck!! He was one of the first to break 500 with a stock truck other than BSM.
Definitely good ol days!
