I'm also running the MP8 and that's what I thought would do the boost fooling.

I've been having a problem with boost on my quad race on my 06 as well. I rarely get over 30psi. I thought about switching to the smarty or stacking them, but if you guys still can't build boost there might be some other problem

Serial # 36292 owned by Luvnacumns is Good To Go.

Serial # 37152 Sixpack73 has wrong diodes and needs to contact Roark for a quick fix!

Serial# 37727 E-Train has the same issue. Call Roark.

We will probably ship a replacement to you and you send those back to us.

Quad did you get my PM?


Don't mean to thread hijack, but do any of you guys have the fuel pressure kit installed? What are you seeing at Wide Open Throttle, mine sticks at 24021 and doesn't move anyone else getting this?

Never had injection pressure sticking??? Wonder if that is some of the problem? Even at that you should be able to hit higher boost than that.

Ok, here is what I need to do. I am going to install one in one of our 600 series trucks. I am going to test the boost and I am going to test the injection pressure. Once I know it works without a doubt I will send it to you and see if it still does the same things on your truck. If that does not work then something has to be funny on your truck. That will suck if that is the case!

Luvnacumns........I might have an idea. I will PM you!

Quad customer service is awsome. I don't have a programer (scared to lose my warrenty) but if and when I do get one, I am sold on Quad products.
