would you recommend this with a agp wastegate ? or will a stock wastegate be able to pull higher boost numbers with this ? i am trying to get up to around 19 psi wasn't sure if i needed to run an aftermarket wastegate if i used the boost box
customer service rep
The Boost Box is designed for use with a stock wastegate however you can use it with an AGP wastegate as you can adjust parameters in the Boost Box to accommodate for any desired boost level based on your wastegate.

can this be used to control an external wastegate on a big turbo setup?
customer service rep
The N2MB boost box completely takes over boost control. It uses the factory solenoids to control boost like the pcm did, however, this gives you full control over boost.

Assuming I have no boost leaks and a properly functioning turbo, can the boost box eliminate loss of boost in 3rd gear as is common with stock SRT4 turbos? I run 19psi through 1st and 2nd but lose boost about halfway through 3rd, ending up at about 16psi going into 4th.
Customer Service Rep
The drop in boost pressure at the top end of 3rd and 4th gears happens because the pcm lowers boost pressure for safety, and due to the stock turbo just not being efficient at high rpm, high boost levels. No matter what you do, it will always drop in 3rd/4th. The boost box may help, but it is used mostly for you to gain control of boost levels, and improve traction.

How do I set this up with a 50 trim kit? Do I have to figure out the solinoids? Previous owner bypassed most of them
Customer Service Rep
Yes, you need to have working solenoids in place to be able to control boost with the boost box since it uses the factory solenoids.

With 7psi spring on external wastegate from agp kit, will this boost controller will be able to hold 25psi?
I wanna run 7 psi spring to have that boost on 1st gear and then hit about 25psi on 3rd and up gears...
