recived and installed flash tunner tonight, everything runs excellent, the only scare was the very first upload when uploaded and came to start the car it didnt. it was on the p2 8psi, so I loaded p3 10psi, then it worked, then I loaded p2 again and the car started as for preformace I was expecting wheel spin off the mark with traction off, to be honest not much different to stock on p2 and p3, I noticed better gear changes and fans turn on more frequently. id say im noticing about 15% more power nothing that you say wow to. things did b4 install, spark plugs 0.8 gap, took actuator out and sprayed wd40, took car for test drive b4 tune load and noticed better preformace than b4. then I loaded the software.
