Hi everyone,
I created a profile on this site with the hope that someone more mechanically inclined than myself might have some insight for me. I've had my 2015 V6 for 2 years, no issues at all, regular oil changes. Most of the time I've had it I've been running the 91 octane tune by diablosport.
About a month ago I installed the Spectre Cold Air Intake (I understand this is actually a short ram). My finding is that from a cold start or at high rpms driving through the mountains it felt a bit more responsive, a bit quicker, and makes a great sound. On the flip side, it lost a crazy amount of torque down low once the engine bay heated up (0-60 time jumped all the way up to 8.1 seconds). I decided I was ok with this tradeoff since most of the time I spend at low rpms is on the highway with the cruise control on, my fun is in pushing it on windy roads.
I did want to reduce the low power, however, so I covered the intake tube and heat shield in gold heat reflective tape and removed a fog light and ran a duct tube from there to just under the filter. This almost totally negated the issue, intake temps are usually about 6 degrees above whatever it is outside even after the engine has been warm for a while. Eventually it will still get heat soaked, but this is taking hours instead of minutes.
So, I thought I had done quite well especially since I have no mechanicing experience at all. Today, though, when I pulled out of my driveway and onto the road and started accelerating, there was a pretty jarring thud and my car slowed quite a bit quite suddenly. My window was down and I mostly heard it through there so I couldn't pinpoint where it came from though it felt like it came from the front half of the vehicle. I wasn't expecting to have to log my experience driving to work today so this won't be precise at all, but I believe it happened somewhere around 3000 rpms, right where my car starts to feel speedy.
I turned around and parked it, popped the hood, looked in the engine bay and under the car for anything out of place and I didn't notice anything unusual. I tried googling what happened for about a half an hour with no luck before I needed to get to work. It should be noted I ALWAYS drive in S with the paddles, I just can't stand letting the car try to figure out what I'm doing. When I left, I did not experience any issues getting going on the road but I was nervous and had not activated the manual shifting mode, it seemed to shift out of first and into second very early to me.
At the bottom of my road, I stop and turn onto the highway. I usually accelerate quite hard to get into traffic here and today was no exception. By now I had taken over the shifting since all seemed well and again, around my car's torque peak in 1st gear there was a jarring thud. At the same time it happened, I was just starting to pull the paddle for 2nd, but I ended up in 4th instead. It seemed to me that whatever the car went through caused it to turn off manual control mode and it put itself in 3rd with my immediate input restoring manual control and shifting it up to 4th.
This has me deeply concerned as it is my only vehicle and I live about 10 miles from work, I also don't make a whole lot of money so I'm stressing pretty hard. I haven't driven home yet, and I plan to take it to the shop tomorrow morning. Of course I'm hoping the professionals can figure out what's going on and fix it if it wasn't just some sort of fluke, but I'm driving myself crazy so I wanted to ask for input here. I'm also not really confident the local shop will do anything, I live in the middle of nowhere and I've been burned by them before.
Neither instance caused the check engine light to come on, I checked for codes with my tuner just to make sure and there were no codes. I also should have mentioned that I'd been missing my tuner for some time (thought it burned in a shop fire) and found it today. I checked for updates and reapplied my tune just before the first incident. I reapplied it again between the two thinking it may have been possible the first time was some kind of glitch-instigated problem with the tune (I learn quick but I seriously have very little mechanicing knowledge, so if that's a stupid thing to think don't ridicule me).
Any thoughts for peace of mind or helpful things for me to suggest to my sketchy small town mechanics?
