Hey guys I have a glk350 4 matic 2010 and I'm looking to enhance engine performance whether it's a chip or anything else I can do? Please help me with any suggestions or anything I can do because I cant seem to find anything on it. Thank you so much guys!

It should be fast now, kinda dumb to want to beat up a 9 year old mb for go faster, and ruin it. Yea put in a chip and wear it out. Mb are cheap to fix

Haha thata tru just a little but of extra horsepower would be nice do you know what chip is best to use or anything else? Please and thank you

You don’t say whether you’ve done all the required maintenance on it. Bad idea to flog an older car that hasn’t been properly maintained.

Why not start with spark plugs, injector cleaner, fuel and air filters, clean the mass air flow sensor, clean the throttle body, correct spec synthetic oil change, and run premium fuel always. Also note that older exhaust components will be getting full of crap after about ten years. You may benefit from a new cat converter and oxygen sensors.

Might not be cheap, but all of the above are meant to restore the power and performance your MB left the factory with. Taken care of properly it’s no slouch.

Oh ok thanks you car has been properly maintained only has 90 000 k and only fill up with 94 but yes I'll do all of that aswell that you suggested

Also I'm making it looks nice with some rims and 1.5 wheel spacers to give it that aggressive look how do you feel about that and ski rack with cross bars with a over hang. Silver and black is the color scheme

Drop an AMG V8 in it.

Haha how much would somthing like that cost me?

This.

OP: spend your money however you wish. If it was me, I’d get caught up on all maintenance and run diagnostics to make sure everything is performing per specs.

If your GLK is slow, something ain’t right. Even stock they put out about 270hp (later models 300hp I believe) and that’s plenty quick.

Yeah mine definitely isn't or doesnt feel like 270 I should get proper tune up first your right. How much is usually a full tune up for this kind of car

Would you happen to know why my fan keeps staying on even when I turn the vehicle off it stay on for about 5 minutes and the temperature gauge reading fine coolant level is fine. I just put hidights in yesterday you think that has somthing to do with it?
