1500 w/ Haltech boost control
 

Searched but couldn't find anything current.
External or Haltech Elite 1500 for single turbo boost control?
Thanks.

Not too sure on what you're asking but if it's whether you should use an external boost controller or use the ecu for boost control, the answer is use the ecu

That's what I was looking for. Couldn't find any info on if the Haltech was the best route or not.
Thanks.

Is there any provision for easily switching between boost levels without a laptop?

Yes, setting up a knob on the car and having it control boost levels would be easy.

Haltech has plenty of good YouTube videos about their stuff and they have an episode each on both of these. One is using closed loop boost control and the other is something like turn it up to 11.
