Hi there,
Upfront: The car is a 1989 Lebaron 2.2 Turbo II GTC. It has a straight through 2.5" Exhaustsystem (with high flow cat). Also I have a BOV and G-Valve installed (currently at something around 10-12 psi (using the Chrysler built in Boost gauge). Whatever it is, it was the preset as I baught it.
For the rest the car is basically stock.
However since having installed the G-Valve I am experiencing a lack of power at full throttle. Remember I run it at its preset level (10-12 psi). It is as if it would be running rich. At all other throttle positions it feels very responsive and performing great.
Now my question: At full throttle, I beleive to know that the Oxygen Sensor is ignored for the fuel delivery. Does this apply for the Map Sensor as well? Or in other words, does the SMEC at Full Throttle always give the max amount of fuel regardless of the boost pressure?
Thanks for letting me know!
