I got most of my Radix kit stuff and wanted to know if I can change the fuel pump and drive it to work & back before I Install the radix and change the tune. Does going to a higher volume pump change anything? (If thats all you chane???) It'll only be 11 miles each way, but I don't want to screw anything up.. Thanks

 

I did exactly what you speak of to my truck, and had not an issue (took my laptop for tuning just in-case, but she made it home like nothing was changed.) I have a 2004 4.8 Silvy... not sure if that would make a difference, but im pretty sure that the FPR will take care of ya...

 

I put my fuel pump in a few weeks before the rest of the kit. You will have no problems.

 

Thanks, Those are the answers I was looking (hopeing) for!!!!!!

 

Unless you alter the FPR, I see minimal issues if any.
