    Say hello to a new vendor and a new tuner on the scene, Miami Tuning Group. Many of you have seen a lot of S63TU tunes have hit the market in short order as F-Series ECU's have been cracked. What will separate these tunes is namely pricing and features. What is nice to see here are timeslips accompanying the dyno chart. How about cracking 130 in the 1/4 mile with just a tune? This is a Florida result so keep in mind the fuel is 93 octane pump. The M6 turns into quite the beast with just a tune so imagine the possibilities with a race gas tune and bolt ons. Regarding the output figures the S63TU goes to 588 wheel horsepower from the stock 524 wheel horsepower. The peak torque figures rises by just under 100 lb-ft of torque at the wheels getting very close to breaking 600 lb-ft at the wheels. You should also notice the torque gains are through the entire curve. Expect to see more MTG over the next few weeks.

    Hi tjav you have the right idea but some things I need to add. Your centri puts out a ton of heat, that is the nature of all compressors, the intercooler will cool down the air using ambient air as the sink. The inlet temp of 148 is actually not terrible. You could probably get away with better IATs using some of these methods. Reduce the restriction to the inlet of your centri (if any, I dont know your setup very well) Make sure your centri is grabbing cold air (again, specific to your setup) Make sure your intercooler is seeing ambient air Make sure your intercooler doesnt see huge pressure drop across it which in turn will cause you to not hit target boost vs. impeller speed. Unlike a turbo that actually has a closed loop boost target using a wastegaste, the impeller speed of a centri is fixed with engine RPM, a turbo can vary impeller speed to attain boost using wastegate action. All of this means basically a restrictive intercooler in front of a centri blower means less boost, a restrictive intercooler in front of a turbo tries to attain same boost (and it will) but more heat (more impeller speed to attain target boost). This is difficult to measure unless you have the right data logging equipment, measure inlet air to IC and outlet air to IC, measure inlet pressure to IC and outlet pressure to IC etc... Methanol injection is single most effective way out of all of the above. If you must. Also, it doesnt hurt to know your impeller speed which you can calculate based on your centri gear reduction and pulley diameter and engine speed. Excessive impeller speeds leads to excessive temperatures, all this can be analyzed if you give me the compressor map for your centri. I doubt though, this will be an issue for only 7 psi unless the centri is undersized. Hope this helps

    Just got around to looking at this thread. DBFIU is probably who you want to talk to about this
