You are not sure if your UEL is tuned? and wondering why the stock header is working better?

Have you gone through the process of logging and getting revisions like you were supposed to?

FYI, a EL (like stock) will always feel smoother than a UEL (your aftermarket header). UEL's rumble/vibrate, which resonate through the chassis.

Additionally, a quieter car will ALWAYS feel faster, because you can step on the accelerator more without "hearing" as much acceleration, but feel more.

Missed this post earlier but I think I may have noticed the same thing... What exactly feels less smooth with your UEL over the stock header?

Thought I had a bypass valve issue but after performing the test of squeezing the vacuum line connecting the valve at idle I didn't notice a change or hiss... I just recently swapped over to the UEL and throttle tip in seemed slightly more abrupt than when I had my stock manifold, although the car does feel like it has more torque so I was wondering if it's just the additional power. Throttle modulation (as long as you're starting from a throttle position other than 0%) is smooth. Car had additional logs/tune revisions put in place after the UEL install.

Am about to go e85 and have a new tune to go with it, I'll report back after that's been installed.

Lol it's interesting you say quiet cars feel faster -I've been in a few straight piped cars (not twins) and the shear assault on the senses always makes it feel faster to me.

On my car, I noticed the UEL rumble (which is awesome), but throttle tip it feels like the car lunges forward abruptly. Kind of reminds me of my sportbike when you roll into the throttle in a lower gear, it kind of jumps on you right when the throttle plate begins to open, even with incredibly smooth throttle input. I've gotten used to it, but it is noticeable. I kind of thought it might have to do with the bypass valve closing and the boost engaging, but that's just another theory...

I agree with that. That slight supercharger whine combined with the sheer force of acceleration that I feel on my neck is so awesome. It feels unreal like a spaceship.

Yeah it's funny because it's definitely not sound(not that stupid) nor is it throttle modulation, it's definitely quicker with the stock header. My car is also more smooth with 91 octane but faster with e85. Just with the header and e85 my car just feels like it has spotty acceleration. To put it into perspective, I do have timers on my acceleration to 60 and 100s and they are a little quicker on the stock header. Reading on my past emails with csg I believe I "should" have the uel tune considering I listed all my mods when they asked for it. Who knows.

What UEL header do you have?

Yes, Ecutek still only runs on windows, with no plans for a MacOS version.
