Re: Terrible Experience With OBD-Tuning Pte Ltd!!!
yes charts can be altered easily by the dishonest (thus u need to see the tuner track record, ability to tune different type of turbo settings, injector values, advance/retard, compressor efficiency knowledge, AFR values and nt just someone who just know how to advance the timing by +2 at certain RPM)
dyno on the same day , before and after and take note of the humidity and correction settings, make sure they are the same. some tuners like to take stock values at a hot humid day. then after dyno when the time of the day is colder, ie at night.
a dyno is still needed to quantify gains...
