I am going to be putting in a walbro 255lph pump on my denali, my question is when i do is there anying that I have to chance with the tune to correspond with the pump? Or can I simply put the pump in and drive? I cant think of any reason that I would have to change any of the tuning but with these things the hell if i know. Help..

 

Anyone??

 

Someone has to know the answer to this...

 

If anything, you might run a little rich. I wouldn't worry about it.

 

Yeah it is better to run a little rich rather then lean especially if you are going to run a supercharger.
