05 GT, Eforce supercharger tuning questions
05 GT, Eforce supercharger tuning questions
I purchased an 05 Mustang that was already built and tuned by the last owner. The last owner passed away before he fully completed his/my supercharged mustang. The car runs awesome and I have pulled away from a new z06 vette, the current tune is pretty good.
There are some things however that need to be adjusted that I just don't know how to do. The warm up cycle is super rich. I am an extreme newb at this and am eager to learn so any help will be appreciated! I will also share my existing tune to help others out! I just wish I knew all the mods on the car. It has comp cams phaser limiters, so it might be cammed. It has a 2.75" pulley on the Eforce supercharger, 60lb injectors, longtubes, 6 speed manual, some custom read all pids on the stock odometer readout, lots of work done. Thanks

That charger came with a factory tune designed for a stock engine which is perfectly fine to begin with. When you modify the engine further, the tune no longer works as you are finding out. Your only solution is to find a professional engine tuner with a dyno and have them re-calibrate your tune.

I have the the same blower and it was custom dyno tuned. My tuner left mine a little rich also but said it was on purpose as it is better to be a little rich than to run lean. Like others are telling you the right way to fix it is have someone do it. To risky to mess with yourself they will also see if there are other areas for improvement. This is best especially since you don't know the history of the car. Mine makes 500 horsepower to the wheels, you want it done right.
