OE Tune Review

Tune (no matter who) + Serious failure and you're on your own.
OP -- Thanks for the insights. From the majority of reviews out there OE seem to be praised as giving a bigger kick. That EC V5 blip tho... Sounds pretty amazing.
As for this whole bench vs obd... There is no difference other than bench tuning being so inconvenient. You have to ship your ECU around the country and trust that it finds its way to the tuner and back to you. Not to mention not having a car while this is happening.
OBD is simple, easy, and the technology is there. Put a Renntech tune on your car. Then do OE. Other than maybe a slight difference for or against one of the companies in terms of performance, you will notice zero differences in the method with which the car was tuned. Not to mention if you have a handheld you can flash back to stock if you have to or bounce around maps. You don't get this with bench tuning.
+1 for OBD
next meet is AUG 3rd
hopefully weather is good

Does OE have the option for the blip? or is that special to EC? Video?

I contacted Jeremy for one of his tunes a couple of months or so after my car purchased. Back then, my OE tune arrived a day after my new K&N Filters. I installed them both and drove around for almost two weeks before strapping on the dyno where I did a stock vs. tune test and noticed the gains. So to answer your question more directly, NO, I did not have any other mods besides the tune and K&N filters w/o CF filters...that's it.
It means it pulls even harder and it makes the trans shift a little harder as well while holding gears a little longer. And, maybe its me, but it seems to make the car sound a little louder as well (in a good way).

What is so complex to you?

Just choose a tuner and let them do what they do and that's it.
BTW, bench tuning is no better than OBD tuning. OBD is painless and it takes like 2mins to load up. However, live in person DYNO tuning is much better than either, but that is not always an option.

This may start a war, but I dont care, in my opinion, Renntech is overpriced like a ****, so is AMS in Chicago
The only tuner in the industry that I know will do this is Dinan.
Some say Dinan is overpriced but there is no denying that their engineering is top-notch.
Furthermore, they offer a warranty that matches the BMW factory warranty. Several years ago, I had a Dinan High Capacity Oil Cooler (and Dinan Stage 2 Software, etc.) on my E90 335i w/ N54 motor. The oil cooler developed a hairline crack (cooler was leaking oil) and when I took my car into my local BMW dealer, Dinan sent a new oil cooler, BMW spent the required 8+ hours of labor to fix it, and Dinan paid for the entire thing.
There was zero hassle.
Another guy I knew had Dinan Stage 3 Software (and a Dinan Intercooler, Oil Cooler, etc.) and his wastegates failed. Dinan paid for the entire $12k+ service bill, no questions asked.
OT but interesting nonetheless, IMO.
So before I talk about the actual car. I'd first off like to say that Jeremy, is a class act and from the moment I spoke to him, he never "pushed" me to buy a tune from him. The decision was in my hands to pull the trigger. I looked at all tuners... Renntech, Weistec, AMS since, I'm in the Chicagoland area.
Now for the actual tune. **This is how the car should of been from
the factory!** When I first loaded the tune. I couldn't really tell if I was tuned or not. I felt the throttle a little bit more in tune with input and the start up from the car was slightly louder (nothing crazy). As, I slowly started driving and gave more gradual throttle, it was apparent that it had more pull. About 20 miles into driving it, I put it in S+ and it was apparent that it was making every bit of claim that OE has told me. I nailed it on a on ramp at 25 mph and I was totally blown away! The tires just broke loose and they are brand new pilot sports! The pull from idle to redline was breathtaking! Three digit speeds come up very quickly now. Every little bit of aspect of the car was changed...Low-end, mid-range and top-end.... Doesn't matter where you are in the powerband... It just rips, throws you back in your seat, while you cling on for dear life. I opted for the 7300 rpm redline and the pull up top is just awesome, in fact that is an understatement... And, the gear changes are BANG, BANG, BANG! No hesitation! The car has fully adjusted to the new tune now and the car now seems faster than first loaded. Which is expected. I am eager to see how the race file is... 😈
I couldn't be more pleased 👍
Furthermore, I have driven a c63 with a Eurocharged tune. And, like it or not, the OE tune, IMHO is better. Not saying that eurocharged is bad and no need for it's fanboys to run to it's defense. I thought it was very good! I just feel OE suits the type of driver, I am and what end result, I'm looking for from this car. If I didn't like OE I would of happily bought another tune from someone else. Hopefully, this thread can help some guys out with their decision on who to go with.
Again, I am extremely happy with the OE file and Jeremy's A+ service!
Have a good rest of the day guys!

Again, you and I see eye to eye here. Both are quality and neither really have any drawbacks.
I will be in the tuning market shortly and will be open to letting tuners sell me a tune.

Both, are great. I personally give the edge of performance to OE.
I wouldn't hesitate to give Jeremy a call if I would tune another car of mine in the future! I'm that confident with him!
At the end of the day pick your poison! Mine is OE. Seems more lethal 😈
