I am still running on my original motor and tubos with close to 100k miles. Pettit DP, Pettit Intake, Pettit Catback, stock cat and pullies. I am Currently running on the PFC Base Map that it comes with on the stock boost. Anyone think it is worth getting it tuned or getting a better map that matches my upgrades? Actually does the base map that comes installed on the the PFC pretty much match up to my basic upgrades anyway? Or should I just wait till the motor goes and do it when I get a rebuild? Car runs better with the PFC base map than the OEM ecu, But I would have to imagine that tuning would make a huge difference. Just not sure if it is worth it due to the high miles and approaching rebuild time. What do you guys think? Thanks for the input.

 

I wouldn't touch it! You are on borrowed time now...lol
Just enjoy it like it is, it is obviously not hurting anything if you've got 100K on it!

 

If you would be porting the motor when you have the engine rebuilt, then wait. If you intend to not make changes when your motor is rebuilt, might as well tune it now.
