So I ordered SCT BDX tuner with Steeda tunes for life for a 2016 GT. I have Texas Speed catless headers on order. When I was filling out the tune form I noticed it said "This will not turn the catalytic monitors off". Does that mean I can't use an offroad midpipe? If that's the case should I get high flow cats or put my money into a ported intake? Is there much power loss between the off road and high flow cat midpipes? The headers are on back order so it's not to late to change to high flow cats or go with a manifold instead.
