The first step in troubleshooting is eliminate as many variables as possible. In this instance, the indicated step is to load up the Magnuson tune, run it as it was meant to be run, and see if it is an install issue.

Is your current nelson tune even setup for the radix?
It sounds like he had an N/A nelson tune, installed the Radix, then couldn't dyno tune or install superchips on top of it. If so..... Running the radix with 42# fuel injectors on a 'hot' stock tune would completely explain the extremely rich condition, the dyno misfires, the catalytic converter failures, and low power numbers. 40 hp is good in that light, but its stupid to dyno (much less drive it at all) on the current tune. Feel lucky it was only failed converters.

If that is the case that sure would explain alot.

BTW, I am 100% satisfied with the stock Magnuson tune!

The other lesson is don't waste money on a dyno unless ALL bugs and tuning in the STFT is worked out, especially if you put a supercharger on and still have a NA tune. YIKES

I plan on running the supplied Magnuson tune when i receive the "unlocked" computer. Boost is stock 5-6 psi.
As stated previously i already had a Nelson tune for my mods which ran well, but due to the fact that he locks his computers out i couldn't have started with the Magnuson tune even if i wanted to.

Look at it this way.... as long as nothing else is hurt on it, you are going to be real happy with the results after you get the new tune.
You know, you can have a dealership update the PCM with a stock tune (overwrite the nelson), then you can upload the superchips. You might even get the catalytic converters replaced under warranty since emissions equip has like an 80K mile warranty. Then you could be driving it today.
