Performance by IE Reviews

Been driving it every day and it’s been super smooth. No weird issues so far, just feels easy and comfortable to drive around.

My order showed up packed well, and thankfully nothing inside was loose or damaged. The box did have a small dent, which made me a little nervous at first, but all the parts were totally fine. I’ll keep ordering for now, but if stuff starts showing up damaged, I’d probably have to look somewhere else...

the parts themselves were totally fine, but the software gave me more trouble than i expected. it took me a while to figure out the updates, and the menus felt clunky. support was helpful enough, but overall it was just more annoying to deal with than i hoped.

I ordered from Performance by IE, and the shipping was a little slower than I would’ve liked. I’ll admit I’m kind of impatient when I’m waiting on parts, so maybe I noticed it more than someone else would, but it did take a few extra days beyond what I expected. The package arrived in good shape and nothing was damaged, so no complaints there. Tracking just didn’t update very quickly, which was a bit annoying. Overall, not a bad experience, but not especially impressive either. I’d give it 3 stars.

I did get it installed in the end, so that’s good, but the instructions could’ve been a lot clearer. I kept having to stop and figure out what they meant, and a couple steps felt like they were missing little details that would’ve saved me time. It wasn’t impossible or anything, just more of a hassle than I expected, and it definitely took longer than I thought it would

I got annoyed quickly trying to find what I needed. The pages were a bit slow to load, and the menus on mobile felt messy and hard to deal with. Checkout did work fine in the end, but the whole site could definitely be easier to use...

I had to return a part from performancebyie.com and, the process was decent... just not exactly quick. Support did get back to me and they sorted it out, but I did have to follow up once to keep things moving. The refund came through in the end, so that was fine. Not a bad experience overall, just... yeah, it could’ve been a little smoother.

After using the IE stuff, my car genuinely feels quicker, and I was way more excited than I expected to be. The power gain put a huge grin on my face like I’d just unlocked a secret mode or something. That said, the setup wasn’t exactly smooth sailing. I had to stop and double-check a few things, which was a little frustrating in the moment. Overall, I’m happy with the results, but the process wasn’t perfect. Not bad at all, just not mind-blowingly amazing either.

The prices were fair overall, not exactly the cheapest I’ve ever seen, but I guess you do get what you pay for. The quality actually seems worth it, which is always a nice surprise these days.

I got this mainly hoping it would sharpen up the throttle response. It does feel a little quicker getting off the line, especially in that first half-second when you tap the pedal, but it wasn’t the big difference I had built up in my head. Install went smoothly and everything lined up fine, which I appreciated because I’m the type who notices when a connector feels even slightly annoying to seat. No warning lights, no weird hiccups, and it’s been working fine so far. Overall it’s decent, just kind of middle of the road for me

The build feels solid enough to me. I wasn’t expecting anything fancy, but it doesn’t feel cheap or flimsy in hand, which is really all I was hoping for. I did spend way too long comparing little details before buying it, kind of like when I’m at the grocery store staring at two nearly identical jars of peanut butter, but anyway, I’m happy with it so far.

I’ve ordered parts from them twice now, and both times everything showed up just fine. The packaging was in good shape, the parts were exactly what I expected, and there weren’t any weird delays or issues. I’d trust them again.

the fitment was exactly right for my car, which was the thing I was most worried about. The info on the site matched what I received, and I didn’t have to deal with any guessing or extra random parts. Install went smoothly, everything lined up like it should, and it was just nice having a part fit right the first time. I’d definitely buy from Performance by IE again...

The parts info on the site seemed decent, and for a basic order it probably would’ve been enough. But in my case, I had a couple of fitment and tuning questions, and the replies I got were short and didn’t really clear things up. They may know their stuff, but it didn’t come through in the support I received. For performance parts, especially when fitment matters, I was hoping for more specific guidance

I wasn’t very happy with the whole experience. It started off fine, I guess, but then little things kept piling up. Too much back and forth. More effort than it should’ve been. By the end I was just annoyed and ready to be done with it. I don’t really see myself buying from them again

I installed their tune and was excited to see what it would do. The car did feel a little smoother right away, so I figured things were headed in the right direction. About a week later, I got it on the dyno, and that’s where the excitement kind of faded. The numbers came in lower than I was expecting, especially for what I paid. I reached out to support hoping for some real insight, but the replies were basic and didn’t really help much. It wasn’t a terrible experience, and the car isn’t running badly or anything, but overall it left me feeling disappointed for the money

I’m still waiting to hear back about the warranty, it’s getting a bit frustrating. I understand these things can take some time, but a quick update would be appreciated. At this point, I just want to know what’s going on and when it’ll be resolved.

I was expecting to wait around for a while, you know how support can be, but they got back to me fast. I had this one issue that was bugging me, and somehow before I even had time to overthink it, they’d already helped me sort it out. Simple, quick, and way less stressful than I expected.

I ordered the part because the site showed it was in stock, then later found out it actually wasn’t available. I ended up waiting with no real update or clear date, and I had to keep checking on it myself. Maybe this is just how their inventory system works, but if one item can show as available when it’s not, it makes me a little hesitant to trust the stock status on anything else. Frustrating when you’re trying to finish a car repair and just need the part to show up

After having some work done on my car, I ran into an emissions readiness issue and wasn’t sure what the car was trying to tell me. It was one of those little problems that makes you feel stuck because everything seems fine, but you still can’t move forward with inspection.

The info I found on performancebyie.com helped me understand what actually needed to be checked and what just needed time and driving before testing again. It wasn’t overly technical or confusing, which I really appreciated. Sometimes just having things explained clearly makes the whole process feel a lot less stressful.

After driving for a bit, the car finally showed ready and I passed inspection without any drama. I was really happy with how it turned out because it saved me from a lot of guessing and reminded me that the right information can turn a frustrating car issue into something manageable.
