Has anyone out there successfully increased the power of there 200 with a remap or control box? I've contacted several tuning shops with varying replies - some happy to offer "chips" or rolling road remaps or control boxes but others,notably GAD tuning not tuning this engine. Most worrying was GAD's response to my enquiry saying they did not tune this engine as it was,in their words,"a weak engine" without elaborating on their statement. I have tried to get them to say what areas the engine is weak without any success ie.no reply to emails! Obviously I don't' want to create problems for myself by remapping somewhere else. Brabus are quite happy to add 20 BHP with no mods other than a control box and 40BHP with extra cooling so they must be happy the basic engine will take the strain. I understand this engine has been around a number of years in various guises so I would have thought Mercedes would have sorted out any "weak" areas. Any advice will be appreciated.
Fitted a Racechip Pro2 to my SLK 200 R172 year 2012 about a month ago now,but only yesterday did i take the car for a proper sporty drive to the Evo Triangle Wales UK (120 mile or so round trip i think),a place i really like to visit,i spoke alot to Racechip themselves via Emails and they answered all my questions over several weeks of slowly ajusting the chip on daily runs and such,anyway i have took the performance level up to what Racechip say is its level 3 performance setting(left dial set to 0 thats 12 o'clock position.
Racechips YT advert says they got 40 or more BHP from my car with their chip i am OFC open minded and they will tell you it depends on different Engine tolerance ect but i know my car pulls harder now in sports mode and Eco feels like it restricts harder acceleration even more now.
Now i am also confused by comments from people who have never even fitted the chip to this car telling other people that Racechip are S---t as i thought they have been a reputable company for some time and the Pro2 chip is around £350 so is not a £20 chip?
I searched high and low to find any review on chipping my car and there is not much out there i can find so i got my Racechip Pro2 second hand on EB £50 and gave it a go myself.
All i can say is i like it and it is not BS on the setting i have it my car is better and i checked with Racechip if my car would be fine on level 3 in it's stock form they said the power they advertised or got on the YT add was on a stock car.
I also had the 2 back boxes deleted on my car stock tips welded back on as i never liked how quiet the stock car was even with its roof down i had to thrash the car above 5k revs to hear anything sporty,the exhaust mod may not be for everybody there is a little drone with the roof down at any constant speed but i would rather hear some noise from the back of the car than the stock setup,cost £140 to chop the back boxes and straight pipe to the original chrome tips,never lost the blurp sound the car made when thrashed on gear up changes either just all a lot louder but can still be controlled by how much your revving the car,next MOT will be interesting as no guarantee yet that it will pass one,i feel it is not excessive at all!and i have OFC still got the back boxes stored so they can be welded back on the car if needed.
I like the car more now with the roof down now it makes some noise when asked to and OFC it will never be a V6 V8 or the fiesta ST ecoboost i had before this(if only you could drop the roof on the ST) but trust me i have the sport suspension on my car too and i feel i have a fair mix of roof down fun now,Oh i fitted the roof mod too £180 used off EB and opening the roof now at 30mph (with great care on straight roads without pot holes)can also drive with rear windows up or down,and 3 clicks on car key fob will open or lower the roof within range of the fob.
These are the mods i wanted for my car and hope this helps anybody who was pondering on such mods!
As for what will happen to my Engine with a chip on, it's removable in 2 minutes and put back to stock with a blank plugin and anybody worried about Engine damage after chipping is like overclocking your desktop CPU do not do it if your not willing to face possible downsides,would i do it on a newer car under warranty? erm nope i would not.
I could not find any facts on this thread to prove a racechip would kill my Engine so i go it alone with fingers crossed,many petrol heads do silly things and if they had not done those silly things they may not have loved their Bat mobiles as much!
0H!and yes i did have the roof down all the 120 or so miles yesterday was warmer in the car than the house i live in.
Main thing i hate about the car is it's Auto 7g plus gearbox Manual paddle shift is BS another gearbox that stops you selecting all the gears you chose it always drops the car into 1st gear at stops although i feel the car should launch from 2nd gear and does so just fine but Yes Auto great for city drives but i miss Manual shift on runs like the Evo Triangle i just did again!
