I was about to have bbk 1-7/8 long tube headers and catted x pipe installed over the weekend to replace my stock headers, stock cats and aftermarket MBRP H pipe. currently my only mods are a JLT cold air intake an 93 tune from VMP performance.
They just sent me a new baseline tune to load onto the car after installing the headers and x pipe, which is just using whatever parameters there are for my current setup which is just intake and aftermarket H pipe, but now i’m guessing they changed some parameter factoring in the long tubes to add to this new tune they just sent me.
They’re telling me just load the new tune on after installing the headers and drive it. I asked if datalogging was needed and they adamantly said no. I trust them because they’re experts and pretty respected in the mustang community but at the same time common sense makes me wonder why WOULDN’T they recommend just one datalog/revision after loading the new baseline tune just to make sure everythings running 100% right. They’re basically just taking my previous tune for just intake, adding whatever parameters they added for long tubes and sending me the file. To me this seems like just a canned tune and the fact they’re not recommending a datalog after makes me raise an eyebrow. Should I insist they do one revision for me after loading the new tune or just let it be?
