I'm currently tuned professionally open source.

thinking about installing an exhaust, how much changes would the tune require for this? can i do the changes myself?

current mods:
test pipe
downpipe open
intake
intercooler
GS EBC
tuned @93 octane.

I have all the software and tactrix cable to tune, just want to know by how much would i need to change the fuel/air tables and what else i will need to do. Thanks

 

When you say exhaust do you mean just a cat back since you already have a downpipe and test pipe? If that's the case then you shouldn't really need a tune. The biggest thing would have been to tune for the test pipe replacing the cat, but if you've already done that you should be good.

 

 

if you already have a quality tune, a wideband, and a datalogger; then adjusting for a catback should be reasonably easy as long as you have a good head on your shoulders and a basic understanding of tuning evos

 

A catback shouldnt make that much difference. Buy if youre talking downpipe etc then yeah the tune could be out, maybe not enough to damage anything but not worth the risk IMO.
