Just discovered this thread. Greatest thread on this forum. Thanks for all the great info, pictures and mod work. Looking forward to see how this progresses.
A local tuning company asked if I was interested in being their sponsor car and I reluctantly backed out. I wanted to see more work being done before I sacrificed my new baby haha

CLA45 Bumps Up 52HP in 5 Mins and Some Video Flybys
Our last update on the Project CLA45 was the baseline dyno and some of the modifications discussed that we will be doing. The first major horsepower increase will be from our VR Tuned ECU Tuning Box Kit. The multi channel tuning box is more than a piggyback unit. These Tuning Boxes have high power data processors that are working in place of factory sensors to adjust according to the car and give you a power increase like a normal ECU flash would. However many of these new vehicles have severe tuning encryption on them so the Tuning Box is the only way to gain power. The CLA45 is tested to increase the 2.0L turbo engine 52hp over stock. That is flywheel horsepower so we wanted to put that to the test on our Mustang AWD dyno. Having tested other Tuning Boxes for cars like the BMW 335I F30 and Mercedes CLA250, we have seen the proven resutls. Our baseline numbers were on point with the typical drivetrain loss and ambient temperature of about 261awhp and 281ft/lbs of torque. Since the Tuning Box kits come with a Jumper Plug to put the car back into a stock configuration, we were able to do back to back testing. With the VR Tuned tuning box kit plugged in, the car then did a dyno of 302awhp and 325ft/lbs of torque. This is a wheel horsepower gain of 41 and 44ft/lbs of torque. With our 20-25% drivetrain loss, this puts the gains spot on!
Now the big improvement is how does the car drive? Since boost is increased, and ignition timing with fuel is changed, the power is noticeable immediately throughout the RPM’s. The car revs out much quicker with the turbo spooling faster driving you back into the seat harder. To further test the Tuning Box performance, we decided to test the 0-60mph time with a Performance Box GPS meter. Now our test was done on a warm summer night of 95F and using our standard of 91 octane. Both of these factors stack the odds against the results. Online tests by media show times of anywhere from 4.5-4.8 seconds. These are usually much more controlled and taken the best from a larger pool of testing. We did 2 runs to see what it could do. With launch control iniated, we went from 0-60mph in 4.5 seconds. This time will definitely improve with cooler temperatures and standard 93 octane fuel by at least two tenths.
So now that the VR Tuned Tuning Box is installed, how about some video! Check out all the pictures of the install and dyno tests below and watch our runs. Buy the VR Tuned Tuning Box here.
do you guys claim this to be undetectable by the dealership?
i was wondering about that too. The piggy back can be uninstalled easily enough but running more boost and fuel and timing changes does the ecu log these different conditions ?

Yes, it is undetectable as it is just reading sensor signals. Nothing is logged. These are in stock and the owner absolutely loves it!
Its Project Car wheel time and guess what company we went with? Niche Wheels of course! The manufactures of the wheel industry have nothing but awesomeness in fitments and styling for every vehicle out there. For our Mercedes CLA45 we wanted to step up 1 size from 19 inch factory wheels to 20 inch styles. If you look back through our Project Car gallery, you will see that we love the thin spoke design. So this new 1 piece forged wheel has a directional fan style of the spokes. The wheels are a 20×8.5 +42 at all 4 corners and feature Toyo Proxes 225/35/20 tires stretched to fit. The 1 piece forged wheel is made from a block of forged aluminum that has been precision CNC machined to this styling. The wheel has then been powdercoated black and has machined finishes to it. We can here your crys to lower it… Thats coming soon! Next up, more horsepower! Check out all our info on the Project Mercedes CLA45 here and shop all Mercedes CLA Parts here.

what offsets did you pick for the 20x9 setup? I have an idea of what I feel is possible with a 9" width wheel. The fact that you decided to stretch and the overall look has me thinking you're runnin a +45, maybe lower. Would be nice to have the exact number though. Also, what do these weigh?

Our Mercedes CLA45 AMG is already wickedly quick with the addition of our VR Tuned Tuning Box Kit and new prototype Agency Power high flow cat downpipe. But to take it up a notch for noticeable street performance we added our revolutionary VR Tuned Auto Flash to the 2.0L dual clutch car. The Auto Flash loads and modifies files via the OBDII port of your car. Its basically taking maps that are already on your ECU and doing what a CD would taking you from Track 1 to Track 3. With the Auto Flash, it enhances the cars torque via the factory torque limiter, improves throttle response, and gives you faster shifting. In some cars we tested we have seen an improvement of 40ft/lbs of torque and some upwards of 20 wheel horsepower. The Auto Flash does not control boost, that is why we run the Tuning Box. The CLA45 Auto Flash kit gets the car revving out much quicker than stock. When the Auto Flash is loaded to the car, it takes about 80 miles of adaptation to really work. Having already loaded the Auto Flash to the Mercedes a week or so ago, we now had plenty of adaptation on the car to test it on the dyno.
Our previous tests are the CLA45 with the VRTuned and Downpipe as well as just the Downpipe and no tune. On our test, we can see that the torque instantly comes into play at the start of the test. There is a consistent gain of about 10ft/lbs of torque till 3600 RPM. The torque then resumes its increase until redline. The dip seen at around 3800rpm is probably slight knock because of the low 91 octane we have. The horsepower is increased from 4700rpm to redline at about 12 whp. The biggest difference with the AutoFlash is how much more quickly it shifts. This is very apparent in another test done on a MK7 Volkswagen Golf GTI seen here[/COLOR]"]MK7 Volkswagen Golf GTI seen here. We will be doing some PBox tests to further show the increase in power parts from the stock 4.5sec 0-60 and 355bhp.
