Want to turn your 2015-2020 Escalade into an Escalade V?

The Project DIY Escalade was baselined in stock form, running pump 93 octane.

The results were about as expected, 14.62 1/4 mile at 94.25 MPH with a true 0-60 time of 6.49 seconds, or about a 6.3 0-60 with the 1 foot rollout the manufactures tend to go by.

The install went very smoothly and could not ask for a better kit or instructions from Magnuson.  The instructions manual is extensive, detailed and full of color pictures to make the job easy enough for your average DIYer to tackle in their driveway over the weekend.

If you are looking for an installer, we have options in the northeast area that can help and work with us for tuning as well.

The bolt on kit is designed to work all stock components, stock fuel system and everything is included to get you up and running.

All hoses, clamps, bolts, and even a few tools were included.  Hoses were all wrapped very nicely as well. 

I have seen and worked with other kits and I can really not stress enough how much better the quality of this Magnuson kit is, not to mention the blower is superiopr and makes more power on less boost than any other kit we have seen.

After topping off the intercooler reservoir, letting the pump circulate to bleed out all the bubbles in accessory mode it was time to fire the truck up.  We flashed on Magnuson's provided base tune and everything went smoothly.  I wouldnt say there is anything wrong with Magnusons base ECM tune, but it is certainly going to be way on the conservative side and inefficient if you are looking to use the new found power as best possible but we will be baselining the truck with the included tune file to see the results to get a better idea how much performance is left on the table without a proper custom tune.

As expected, the Escalade's new found power is immediately noticeable when you put your foot down.  The truck accelerates briskly through the gears and up to triple digit speeds effortlessly now and seems to pull harder and harder as it gets moving.  Otherwise, driving the truck around at lower throttle positions feels like stock and there is not much noise to be heard from the super efficient Magnuson 2650 that is barely being worked out.  It is pretty obvious that the stock transmission tuning is "short shifting" the truck too early into the powerband now as it just wants to keep pulling into the higher rev ranges with the supercharger added.

The supercharger is producing 6-7 pounds fo boost with this setup, the fuel system seems to be holding up without issues, manifold aircharge temperatures are extremely consistent and flat when in boost which is amazing for this style of supercharger.

 Magnuson provides an ECM tune only, which works, but at the same time, seems like it leaves a lot of performance on the table to me,  the stock engine is going to make its peak power pretty low in the RPM range, about 5,300 RPM, so the stock transmission calibration which shifts lower in the RPM range at full throttle works well with the stock engine however once the Magnuson supercharger is added to the engine and the truck manifold gets removed, this shifts the powerband up in the RPM range a lot, typically up and over 6,000RPM, so having a proper ECM and TCM tune that will work with this setup where it shines is going to make a big difference with this setup. The factory transmission tuning is going to have the car shifting far before the engine even see's peak power.  Whats the point of adding a supercharger and 200+Horsepower if the vehicle isnt going to use it properly? 

We ended up having an issue with the factory exhaust so long story short, we did have to put headers on the truck as well, so testing is with magnusons base tune and headers, the weather was nice and cool, 41 degrees, so the truck was performing better than usual and was able to put down a 12.83@108MPH, reaching 60 MPH in 4.38 seconds with a 1 foot rollout.

Not too bad for bolting on a supercharger and some headers, nearly a 2 second improvement over stock through the 1/4 mile however we feel there is still time and power left on the table when looking at the tune file magnuson provides.

Now that we have some baseline numbers it is time for us to custom tune the ECM and TCM to optimize the calibration, squeeze some more horsepower out of the engine safely as well as optimize the transmission tuning with quicker shifts and optimized shift points.

When it comes to building a performance car/truck, the details can really make or break the build which is why its important to have proper custom tuning done on the vehicle to get the most out of it.

We custom remote tune GM vehicles all over the world so working with us to get your Escalade tuned if you choose to go down this path is no issue, we sell everything that is need to get the job done.

Once we are done and happy with the results, we will go back and do some more testing with dragy to see the difference.

After retuning the ECM and TCM, we made another hit, which resulted in a 12.48@112MPH reaching 60 mph in 4.07 seconds with a 1 foot rollout, a very nice improvement.
