I am guessing that if it an '05 model it will still be tier 2. I don't think tier 3 came out until at least '06, but I could be wrong. If so, the only company that I know of that offers a module for the tier 2 10.3 Iveco is Steinbauer. There are two different modules depending on the amount of pins that are in the injector harness. They are not the cheapest module on the market but they have applications for just about anything, and I have never heard of or had any problems with them. An increase in power is always nice, but usually you will also notice less fuel usage under the same operating conditions. I have installed modules on a few tractors this year and kept very accurate records of fuel consumption and have seen some really positive results. Combines won't be going around here for another month or so, but I hope to have modules installed on Case IH, John Deere, Gleaner and maybe even a Lexion combine and will be keeping track of fuel usage as well as productivity.
