The proper mod (from what I read on the MB forum) is to replace the wax pellet in the T-Stat with a 170Deg F (vice a 195Deg F). This allows the engine to get beyond cold start mode faster.
Along with the T-stat mod is to have the radiator fan programmed turn on 25 deg sooner. Both of these mods should have the engine running a lot cooler and helping to reduce heat soak.
I have not installed my spacers yet - I am going to be removing the SC and pleniums - for polishing and to get to the intercooler. I will install when I re-assemble.
Of course this mod is not emissions friendly - but it is performance friendly.
