had intake replaced 97000, manifold pressure switch replaced now it's throws P245B code. Truck has been good up to now, have the old GDP plug and Play with the rheostat switch to turn on or off on the dash. Do not use it much at all. What am i looking at , something left off or not...
I have a 2015 eco with the GDP plug and play which I love. Silly question Here can you use that with the GDE tune to further increase performance or is this overkill?
I was just wondering since the GDE is a tune and the GDP is more of fuel pressure increase from what I have read.
