Will flashing MHD stage 0 with catless downpipes and unmarking oem downpipes on the flash be harmful for my car? I plan on doing this for a long time not just temporary driving on stage 0 or even stage 1. I dont want to do stage 2 and am worried if my car wont run right and start messing up internally etc. (2008 e93 335i). Thanks!

It shouldn't do any harm inherently. But, l would say at least put that kitty to use with Stage 1. Curious, what kind of damages are you worried about? Tried and true tune like MHD shouldn't mess up your car and the ECU should protect itself if something funny is going on. In fact, some will argue MHD is better for your cars reliability. The rest of the group will tell you to make sure you are up on your maintenance, and collect logs, and check for any codes. People mess their car up running crazy tunes/ boost without the necessary hardware, and not keeping up with maintenance.

You will run rich with catless DP's and Stage 0 tune and it will throw a code.

Best bet to run Stage 2 as its meant for catless DP's

From MHD:

Stage 1 for stock cars.
Stage 1+ FMIC recommended.
Stage 2 high-flow downpipes recommended.
Stage 2+ high-flow downpipes + FMIC recommended.

Not sure what you are worried about....

Why would it run rich on Stage 0? I've run 0 with DPs and had no code.

OP, you will be fine on Stage 0 or Stage 1. I've been on 1+ for months with DPs, no requirement to go Stage 2 just bc you have the parts bolted on.

+1 the recommendation to run Stage 1 though. It's very safe and only more fun when you want it to be (with more gas pedal). Putting around town, it feels just like Stage 0 or stock. Also recommend to use the linear throttle option in MHD.

I don't understand why people bother putting cattless downpipes on and want to run stage 0/1, should have left the stock downpipes if you don't want to go higher than stage 1 in my opinion.

This.

Why spend the time and money to install aftermarket parts that allow you to make power if you aren't going to run a tune that takes advantage of those parts, and makes more power?

There is nothing unsafe about running any of the MHD tunes. Run the stage 2, enjoy the big power gains, and enjoy driving the car

Reason is because I drive for work using delivery stuff like doordash and i want downpipes only for the turbo sound and a little louder sound. Im bone stock with a chargepipe and bov and want more sound while not wasting more gas lol

Look at what i told the other person (i drive for work delivering food so dont wanna waste gas, just going catless for sound thats all.)

[iqraceworks]

So you spent $260-$300+ on downpipes.....but don't want to spend any extra money on gas with the stage 2 tune?

On a side note.....I still get 28mpg on the highway running the stage 2+ tune. As long as you are easy on the gas, the stage 2 tune might even help your mpg vs. running the stage 1 tune with the DP's.

Not sure I would care about such a slight loss in mpg (if any) after spending the money on DP's.


But to each their own.....

So only thing stopping from running stock map with catless downpipes is people told ke the car wont run right, the car will run rich, etc and so im not sure at this point. I dont want to do stage 2 bc i deliver food for work

Running the correct tune for the mods you have is probably going to help your mpg vs. running the wrong tune for the mods you have.

And if a couple of bucks a week in fuel is going to break you.....you picked the wrong car as a daily driver.

Good luck with whatever you decide to do .👍

I might get a custom tune with the stock map and have it adjusted so it doesnt run rich. Its from a bmw tuning place,only thing is that does this seem legit or are they just going to give me a stock map from mhd stage 0 without adjusting anything :/ kinda sketchy

Most of mine is city driving, i get 16 as it is lol but i mean it does make sense stage 2 might save gas but it sounds sketchy, like yea ill add more hp and youll save more gas, its true but not for any car or tune, regardless i will not be able to keep my foot off the gas so thats also why i dont go stage 2 plus i deliver food with my car for work.

The only thing that makes logical sense if the whole point is to save money.....is to put the stock DP's back on, then sell the other ones.

Spending $260+ on DP's, then spending $350+ on a custom tune......just to save a few bucks in fuel makes no sense at all.....none. It's like spending $100 to get a free $25 off coupon.

How many miles a week do you drive, and how much do you pay per gallon?

I want the catless downpipes so bad though its the turbo spool sound that I want im 18 understand my perspective, and i deliver food with my car for work so i waste gas everywhere, but spending 300 on catless downpipes one time is perfectly fine with me i can just make it back with working, but gas mileage is going to be everyday when i go deliver food. In the longrun 300 is okay. Does that make sense because if it doesnt then idk but thanks for the help still.

[iqraceworks]

At this point....I'm convinced you are just trolling us.

There is no logic in anything you are saying or doing.....

Spending $300 on DP's is ok.....but you rely don't want to use any extra fuel from the stage 2 tune.....so you are going to spend more money to get a custom tune so you can still run stage 1 and save gas........but you are 18 and can't keep your foot out of the gas anyway......

If the downpipes were $3000 then yea id get wat your saying but i mean i have 300 bucks and can borrow 300 bucks its not a problem. Not saying im rich or anything lol but its not a concern when i can save gas over the years you know

Dude... You control your mpg with your right foot... Stage 0, 1 or 2 won't use more gas... You use more or less gas with your driving style.

Put the stage 2 tune on the car as MHD have designed that for catless DP's, and just takes it easy. Enjoy the extra sounds etc as well 👍🏼

How are you confused, Ill explain: I basically do uber but for food, I want catless downpipes to hear my turbos spool, I dont want to waste gas and go stage 2 because I do uber but for food and dont want to waste gas. So im trying to see if theres a way to this going stock map. But obviously you seem really negative no offense and I doubt youd come up with a solution other than staying confused at what im trying to ask.

Thanks for the advice man, do you happen to know if its safe going stage 2 because all i have is a chargepipe from vrsf with a bov from hks. And of course the catless downpipes. Dont i need to get dci and intercooler

You must be horrible at math. If you drive 200 miles at week, and go from 16mpg to 14mpg, and fuel is $3.00 a gallon.....you are talking about an extra $5.34 a week in fuel.

$300 is no big deal to you (because you can borrow it??), but you are worried about $5 a week in fuel??

And you are going to spend $350 for a custom tune......to save $5 in fuel??

Did you take an home financial classes in school?
