I recently installed a cvf catted downpipe. I bought basic defoulers from AutoZone. After about 2 days of driving, I got a p0133 code for the top o2 sensor sensor 1 bank 1. I want to fix it but everything I find is shown that the code comes from the bottom o2 sensor. I also have a problem where when I drive over 3k rpm and then slow down to a complete stop, my car starts rough idling almost like a cammed car. It shakes the entire car for about 4 seconds and then stops. Has anyone had a... Cvf catted downpipe 3-inch ..read more

Wanted to introduce myself as I’ve been a longtime lurker here but am active on the Ecoboost subreddit. I have a 2020 EB with CVF DP and IC, Turbosmart dual port BOV, UPR dual valve catch can, Roush CAI, Flowmaster FX catback, AM charcoal 19” wheels staggered set-up and new spark plugs. I’m looking to get her tuned soon so if anyone is selling a Cobb AP, I’d be looking to buy ..read more

Hello, new here and in desperate need of some insight. I have a 2015 6 speed Mustang EcoBoost and I am having a issue with my RPM’s bogging down. When the issue first started it was only after fueling. So naturally I replaced the LPS and the evap purge valve. I was still having the issue, took it to a shop they did a smoke test for vacuum leak and checked the purge valve again. Everything check out. So went ahead and had them clean the injectors hoping maybe that was the issue. Still having... bogging issue ..read more

Hello everyone. I was watching some autotopnl videos and was kinda offended by the "bad" reviews they were saying about the Ecoboost, while for cars like the BMW 330e they are thrilled and talking wonders. I smoked a 330e the other day. How the ecoboost feels slow and is laughable while the 330e is an amazing car? I was literally 2 cars ahead in the launch and way more far ahead as the race went on. Although I have a tune at 339hp and 577nm torque. Also I see sites saying ecoboost 0-100km/h... How fast is the Ecoboost really ..read more

I want to get a muffler delete but I’m not entirely sure how it works and which route to go. Do I have to pay the money and buy new pipes and tips to replace or can I take to a shop and they take them off and put regular piping in place of the mufflers and attach the stock tips to the new piping? Or will that sound **** and I have to replace with different mufflers. Want to go with most budget option ..read more

2021 eco boost HPP. I can’t find a way to direct air flow where I want. It seems it only will blow cold to the upper vents and hot to the floor. I took it out on a cold day and wanted to warm my hands and couldn’t direct the heat thru the top vents. It seems to just switch on its own based on temperature setting. Is this normal ..read more

So just recently my 2016 premium has had an electrical fire smell coming from the exhaust and a lot of smoke, but it only happens on cold start and it’s 65°+ outside. The smell and smoke quickly disappears as I drive for less than 2 minutes. I know for a fact it isn’t and oil or coolant smell, the best description is electrical wires on fire. Any help would be greatly appreciated, thank you ..read more

Planning on getting the Cobb access port tuner with the Cobb cold air intake. Will this intake give me more performance? Or is the stock one the best like I’ve heard from some people? Help me out ..read more
