You have the worst blower possible for +2018 so don't even try to run it with GPF - this is not going to work.
For starters you need some short/long tubes with high flow cats or no cats to make some power from this turd.
White smoke? LOL you do realize it's either EURO 6 complaint as it is without any power adder or your GPF will not last long?
Best case scenario it won't make any decent power, worst case cats will get clogged and your engine says bye bye.
Work you way though on your stock OS as Roush OS is no good for you.
