I have 225s and my s363 was pretty laggy until I got my divided up pipes. I think that turbo would be pretty laggy on your truck. I don't see it being very streetable, but I've been wrong before
We never had the gauge hooked up to monitor it, as you can see in the video the truck is pretty streetable. All you have to do is learn to drive on a big single and you can make it pretty smokeless
