AND FYI the Venom 400 really does work. its nothing close to the 25% extra HP but i get a rough 10-15% and it make a big difference when the engine is moving rather then when im sitting at an idle.
I have been having some interference between my MAP and TPS somwhere along the line when i installed my Venom 400. For those of you who don't know the Venom 400 plugs into your TPS(Throttle Position Sensor) and MAP sensor by doing this is detects the throttle body position and when it hits a certain point adds more voltage to the line heading to the ECU from the MAP sensor telling it that the throttle is open more then it is. In a shorter version it pumps more gas in the engine. anyways I am getting some problems when the system is plugged in to the TPS and MAP even though there is no power going to the Venom. when I unhook one of the wires from either the MAP or TPS or both the engine stops running rough and runs normal. how do I solve this interference problem?
