Question for changing charge pipes and intercooler
 

Hi all, currently I'm running an original bell engineering kit with the old miata link ecu. I'm sick an tired of the routing of the charge pipes and the stock intercooler. I was going to reuse use the stock pipe with the map sensor to the throttle body, and buy an intercooler with input and output opposite and fab up some pipe to the turbo with a place for my waste gate. The problem I have is I do not want to have to re learn and re tune the car after doing this. I'm not looking for power gains nesseserally but rather an ease of life when working on the car and maybe a little less lag with more direct piping. Do you guys think I will need a retune for this change?p.s. im not putting some big hot boy intercooler, keeping it small for the lag
