For added safety you can insure the package for $3,000.00 for like $15 dollars. We ship out anywhere from 25 to 60 ecu's a month and we have never had a problem.

Also underdrive pulleys don't require a retune as its not changing anything other than undriving water pumps and alternator to free up a few horse based on crankshaft rotational weight.

I think alot of people are asking this question well if he went to the magic table it took him a couple of "retunes" but how does that work for me.

We had software for crossfires ready we simply adjusted the air fuels to make them safe we also adjusted wide open throttle a bit more. So far as the rest of the maps they were untouched.

Another question well my car is different than his car. We know that we are capable of looking at software a whole different way than most tuners out there. We currently have 42 crossfire stock variations based on dme numbers ect. we are able to come within 1 percent between different cars.

Remember this software was tuned specifically for crossfire its not a mercedes benz byproduct. You guys wanted software just for your crossfires and thats what we did.

If you have any more questions please feel free to ask and we will reply to the best of our knowledge.
