Yes, emissions... I just ordered cats from GT550. So, fingers crossed. I will update you guys how it will go.

I asked a seller on eBay if he knows whether cats from the GT500 are compatible with the GT350, and he replied: "They don't have the mid mount on them like the GT350." What does he mean? Is he referring to the vibration damper? *UPDATE* he confirmed that he was talking about damper (which is...

Hey folks, I just talked to a mechanic, and he told me that the cats are damaged on my supercharged 2019 GT350 (Whipple). I also have P0420 and P0430 codes with the current cats. Installing stock cats again is probably not a good idea, as they will eventually fail. So, what cats should I replace...

yes stock cats, as far as I know

Hi everyone, I ended up taking the car to Hans from Deans Performance in St. Charles. Hans is a great and knowledgeable guy. He did a smoke test and found a couple of places where leaks were happening (one loose hose from the supercharger and one cap not fully closed on the supercharger as...

I talked to Mike Post, and he is booked until late July btw. He said it's not tune-related and thinks it might be a vacuum leak or an exhaust leak somewhere, which is pretty much what engineermike said above. I'm talking back to the original shop, and they should fix that under the insurance...

Hey everyone, any recommendations for good Mustang shops around the Chicago area? I'm talking to Wengerd right now and hope he can help me with tuning and any extra work if needed to make the car perfect. Also, my friend recommended https://fluidmotorunion.com, but I didn't find anyone who...

Thanks, everyone, for the feedback and recommendations. I started a new thread here: : Issues with 2019 GT350 (Whipple) after engine swap | 2015+ S550 Mustang Forum (GT, EcoBoost, GT350, GT500, Bullitt, Mach 1) - Mustang6G.com I sent him an email ([email protected]), but he said he would...

Hi everyone, I need help with my supercharged (with Whipple) 2019 GT350. I got it recently with the supercharger already installed. I took it to a mechanic for diagnostics and a Lund Racing tune. The car passed the 93 octane tune successfully, but unfortunately, the engine blew out on the E85...

Current tune is from the same blower but the old engine. I guess the new engine swap introduced a lot of offsets, making the previous tune no longer suitable. And, I can't get a proper new tune before I break in the engine, but I'm not sure if it is safe to drive the car with the wrong tune...

Hey guys, I took my supercharged gt350 back home after engine swap. And have a few observations: first of all, the car runs quieter and more smoothly on idle. There's no smell, and the exhaust is much cleaner, which is positive. However, the check engine light got on. The mechanic said it's a...

I hear you. I think the mechanic place (at least the management) just wants to return the car to me without any "extra" steps. The car is fully E85 capable with upgraded fuel injectors and other components. So, I'll just pick up the car and decide if I'm going to tune it with E85 after the...

Thanks for the great tips! They put "break-in" oil in, which I intend to swap for synthetic after 1,000 miles or so. Yeah, I heard that E85 is easier on engines, but after the incident, I'm a bit shaky about trying to tune it again, at least not right now. I have no idea why it happened. The...

Haha, I know, right? Picking up the car tomorrow. Wish me luck. My break-in period will mostly be in a trafficky area. I checked this video, and it looks like it might be a good idea to try to take it to some clear side roads for breaking in the higher gears...

Hey everyone, I recently bought a supercharged (with Whipple) 2019 GT350. The first thing I did was take it to a mechanic for diagnostics and a Lund Racing tune. The car passed the 93 octane tune successfully, but unfortunately, the engine blew out on the E85 tune (rod through block). Luckily...
