Hey guys. Just curious if Catless down pipes and mid pipes would need larger injectors for a 2015 ?also, I'm assuming an off the shelf tune from Cobb / ecutek wouldn't be sufficient for both dp and Mids unlike mid only?

Thank you for the help.

You wont need larger injectors .. Only a tune 

OTS maps will be sufficient

OTS tune will work but if you can get a custom tune, your car will be happier.....

You sure? I heard that stock injectors are already almost maxed out out off the lot. What would injector duty cycle be on stock injectors with downpipes and midpipes?

Downpipes will max out injectors, with just a midpipe I was getting to 100% IDC!

Unless you have a really conservative tune, you would prob max out stock injectors. If you go E85, its a must.
