This is the adjustable version that is boost referenced and is a 40 amp. Unit works fine as I've daily drove it for over 10k miles with no issues. The real problem with the unit is the programming, this is a earlier unit so it does not prime the pump when the key is switched on requiring the car to be cranked over a couple more times. Theres is supposed to be a software fix at vortech but I never took the time to send it in. Normally a 400 dollar unit ill take 110 shipped because of it needing a update to prime the pump. If someone has a maxed out pump this is good to get on there to save the engine cheap. Can text pictures.
