Ecoboost stage 3 problems

[NoSlowEco]

Alright guys I have a problem/ question. I recently was making 345 hp and 420 tq according to Cobb estimated numbers. That was on Cobb stage 1 with mbrp cat back and k&n drop in filter. I recently installed cvf street Intercooler and catless downpipe and went to stage 3 Cobb tune and now it’s estimated 330 hp and 400 tq. Any reason why I would lose power with the bolt ons and going up in tune? Appreciate any help.

and catless downpipe

Gee Mr EPA, why are you deleting emission components ?

they are just estimates. does the car feel weak or slow? if not, ignore them.

Doesn’t seem any different than when I was stage 1

it should only honestly feel stronger in upper rpms, the catless downpipe lets it free flow at full throttle. if it isn't running bad, its working as intended.

maybe I was just expecting a major difference

idk. im not Cobb. just assuming. unless it runs bad I wouldn't worry. its still an 2.3 using same turbo in 1/2/3

Well don't rely on your cobb 'guesstimate'. Compare your after runs to your before runs. Specifically MPH, from that, it's a simple process to extrapolate HP. Or look at the air loads before/after, also a good indicator.
