jet programmers for 6.0

[1badc20]

I have a 1970 gmc (shortbed) with a lq4, gm hot cam and a pair of 1 3/4 stepped headres, everything else is stock, turbo 400, 9in with 3.50gears and a detriot locker. I was looking at programmers for the ecm, I liked the features of the jet programmer. Has anyone used this before? did you like it?

You are going to be told to not use a hand held programmer. Instead use Nelson Performance - Performance without Sacrificing Drivability
