So I just installed my CPE catless downpipe on my 2016 Fost and I am now fully bolted. I also switched from the stage 2 cobb ots to the stage 3. Granted I know these tunes suck. But I feel like I have less power now...less low end torque also. Is this just because of these crappy ots tunes not accounting for catless downpipes? I have heard rumors that catless downpipes actually make less power than stock when running a stock turbo? Any truth to this? I have a 93 stage 3 stratified tune on the way. But I was just wondering if anyone had a similar experience when switching from stock to catless dp. Thanks for the opinions!
