I think the JET ones are deascent. U actually ship in ur ecu and they modify it with their chips. I think the JET box u buy is pretty much an empty box that u put ur ecu in and ship out to them. I doubt there could be a lot of power from a mod like that. I would invest in different things.

How can the venom mess with throttle. Ours is a cable throttle directly linked to the pedal right? So how can an ECU chip thing mess with that.
