New exhaust, no cats, injection changes?

Hi,

I have a discovery running on lpg/petrol (mostly lpg), I recently replaced the exhaust with a non-cat version but still have the lambdas fitted, do i need to change anything on the fuel delifery side of things, IE ECU etc, and if so why?

Cheers

Nope, no need to change anything, it'll be just sweet as it is.

There are reports (backed with dyno evidence) from TVR land about using a green or red tune resistor in the ECU to get a little bit more power out of the engine. I don't think that's relevent if you're running LPG.

thanks

I had wondered about tune resistors, I have one from a non-cat system but iy had no lambdas so didn't know if it would be ok to use.
