They know what their doing their not experimenting with customer engines like some other tuners. Theirs no long list of Blown engines with Kleemann tunes not to say one their engines couldn't blow up. Their big liablities and bad press involved in blown engines that equal to thousands of dollars that could be lost. And yes a K3 tune or K4 with big tb will support as I was told buy Cory a bigger crank pulley up 178 to 180. I agree bigger injector's 550cc would be a safe guard on the engine with the right cooling .. let this topic go ,, Damm

I have a ported 82mm TTM throttle body and K3 no issues.

The proof is in writing in a data log on a big pulley full bolt on car.
