I checked the Forum for info on emissions testing but they seem to be dated, for Ecobost trucks and almost a year old. My F150 Scew has the Boss install, SCT tunes for the Boss, Flowmaster after cat and cold air intake mod’s. Its 2014 5.0L engine and I need to go and get the tag/emissions test done this month in Texas. So here are the standard sets of questions; Do I put in the stock tune before I go? Should I attempt the test without return to stock? If I go to stock do I need at least 20 to 50 miles before I go back for the test. Will the Boss affect the stock tune and the emissions test since 5 Star says it needs a tune to work correctly. I sure don’t want to have to pull the Boss just to pass the emissions test??

It'll pass without any issues. You're emissions system is still completely intact.

How are you liking the setup?

I like it just wish I had more options on the tunes. 5Star only gives you 3 for the Boss. If you have an EcoBoost you really need a tuner. When I first got my truck I loved the tunes I got from 5 Star but wanted a little more performance without going with a blower - opt'd for the Boss. When I step on it, it turns heads and moves out once you get past the 2K revs. I'd probably opt for for more of a Coyote setup next truck or if ever have to replace this engine. I'll let you all know what happens when I get the test next week.
