For those who are running aftermarket tunnels on Turbo Nytros, I understand many of you are removing the right side tunnel heat exchangers and not using them at all. I am wondering if you are seeing a significant coolant temp difference. If so how much?

You may already know this but i thought i would mention it just in case you did not. Most of the aftermarket tunnels have their own undertunnel U-coolers and take advantage of the running boards as coolant lines. So they are not really gettting rid of the tunnel cooler. in most cases they are adding surface area by running the style of cooler found on most 2 stroke sleds while utilizing the running boards as coolant lines.
I have read from people running the MPI stock replacement tunnel cooler that temps run +/- 30 degrees cooler and most have deleted the radiator as well.

I was not aware the aftermarket tunnels came with coolers which essentially replace the stock heat exchanger. The MPI tunnel cooler is the way to go unfortunately for those running MCX turbos it's just not possible due to the turbo exhaust location. Thanks for the clearification.
Here's a pic of the underside of my Nypex, so you get the idea how it all works. The running boards are heated going to the rear cooler.
