Hey guys just wondering if u can increase the boost on a yd25 with out a chip i allreddy have a 3" zorst just want more boost
Solder in an 8k ohm resistor in the brown wire of the pressure control valve found at the front of the inter-cooler. This will up boost by 10% and get the egt's down. You will see the valve if you look through the grill on the front rhs It has a plug with 3 wires. The middle is the brown one.
Have done this my self.Def help in xtra power but I do run duel chips.
Total cost around 20 cents.
