Maybe thats because Karl has them in for live mapping, because of the method the gunship uses would be a little risky to fire out off the shelf.so the mapping doesn't have to have the safety margins built in to it.

where as most other tuners don't get asked to live map that sort of spec, but simply fit off the shelf chips?

I've not live mapped a stage 1 - 3 car since I've been at MSD.

if someone asked us to live map them a 30psi spike in boost on a T34 803s car, of course we could do it, but i wouldn't advise it, id rather fit bigger injectors, and thats the point I'm making. it all just seems a little backwards.

I could understand it to a point back in the day, where 403s would idle at 9% co, and cruise at 10:1 AFR,so there was a reason not to use them but these days we can use bigger injectors and there are no downsides at all.
