At this point to my knowledge the only sure way to be able to use bigger injectors is with an ECU chip upgrade. The EEC-IV processor of our ECU is not reflashable so that's not an option as it is with other Vulcan equipped vehicles.

SI Valves has stainless steel, swirl polished one piece valves that are FAR superior to the factory ones for just a few dollars more. Check here for my thread on Cylinder Head modifications for the Vulcan, most are DIY.
Copper head gaskets and ARP studs are a must for any real HP quests. Nitrous, Blowers and Turbos eat the factory ones on a regualr basis.
For free:
Advance the timing at the distributor until the engine pings under heavy acceleration, then drop back 1-2 degrees.
Move the ACT (of IAT) sensor to the front of the radiator support to allow it to read the actual outside temperature vs. the upper intake temperature.Last edited by Fredness; November 29, 2004, 12:14 PM.'94 Splash, Supercharged 3.0L, 5sp, 3.73's turning 31x10.5's.
