I have a quick question, I am currently in NYC and I have loosened up all the bolts and ready to remove DPF and other pipe, to install my delete pipes, keeping the down pipe.... my question is this. can I install the pipes, and block off the EGR BEFORE I tune the car ? once I block off the EGR and have the pipes installed can I drive the truck 1/2 block to the location where I have wifi to run the tunes ? or is it detrimental to start the car and go 1/2 block when the new pipes are on and EGR is blocked off... will it mess the truck up? I only need to move the truck into a space that will allow me to run the computer for the tunes, but its 1/2 block away, the place where I am working on the truck for the pipes does not have wifi !!! also would a computer on a hotspot work for the tune ? how long does it take to tune the truck ?
