I have attached the Dyno Results from my Supercharged Silverado. I hope you can all see that this engine and ECM have the ability to be tuned. I am very capable of installing this kit, but leave the fine tuning to the experts. Some may think they are experts at tuning, but use a reliable source, you will be extremely happy with your purchase. By the way, these dyno results were the next to last run, the final numbers were 438hp, 429lb-ft. After the dyno tune, it was determined that I need to install a JMS Voltage Booster for the fuel pump. The proper voltage should be between 14-17 volts, but intermittently, we observed 11-12v which is not allowing full power, so it will be interesting to see what the total HP will be with the booster installed.

I just picked up my truck from the tuner yesterday, and I have to say, this thing rocks. The tune from Whipple (HP Tuner)was not good for this engine/computer, it is a MF (exact words) to tune. My tuner basically creates his own tune and does a large quantity of calibrations for Whipple, which he is sending mine to them to use. The install of the supercharger kit was fun, but would suggest having a hands on tune done. I created a new install post and will list the dyno and driving results in the next day or two.

I am anxious to see what this tuner can do. He does tunes for Whipple and HP, but he designs his own tunes. He and his crew on occasion tune for NHRA drivers, so he is very capable. I will not talk bad about this product until I have the expert work his magic.

This write-up is for a 2017 Chevy 2500hd 6.0l Flex Fuel. I decided to install the Whipple Supercharger system on my truck. The Supercharger Kit comes with very quality parts that are precision made. Now, the install manual needs some definite editing due to missed steps and steps that can be performed ahead of time to save interruptions in the process. I am editing the instruction manual to include time saving steps and will post it when completed. The kit for my truck took 2 days which is not out of the question if your being careful. The kit includes a HP Tuners MPVI-2, supercharger w/ intercooler, intake manifold, fuel rails, heat exchanger, reservoir tank w/electric pump, new belt, tensioner with idler pulleys, MAF sensor to throttle body hoses, new 160-degree thermostat, and all the hoses and electrical wiring needed. It is a little overwhelming when I first laid it all out, but once underway (with so so instructions), everything seems to just fall into place. Granted, I have been a mechanic for over 40 years, but a person with less time can surely do this themselves with patients. This kit uses the stock airbox set-up with a high flow filter. Other than that, most everything is new install. The kit uses the stock fuel pump and injectors. These items on the flex fuel are more than sufficient in supplying fuel to the engine. The very first thing I did was read the stock files in the ECM with the HP Tuner program, then I sent the log file to Whipple via email and within 1-2 days, I received my new tune for the truck for after the supercharger install. The next steps were to drain the coolant, and begin to remove components such as: stock intake manifold, alternator, fuel rails, stock belt tensioner and idler pulley, plus more. There were a few hiccups that occurred during the install. The kit included an older wiring harness that I had to adapt to my truck, (this truck is my daily driver, and I couldn’t wait for the correct harness), older fuse tap, defective MAP sensor (GM part, which is installed before the intake manifold due to the location on the back of the engine), and the intake bulge pipe did not fit correctly. Other than these shortcomings, the install was not very difficult. The install of the heat exchanger and reservoir tank w/ circulation pump were a little confusing and time consuming, but with proper instructions, it should go easy. Once everything was installed, I programed the truck for the new tune. I have been having issues with the tune. After speaking with a professional tuner, I discovered the computer for the 2500/3500hd 6.0L is only used in these trucks. The tuner explained that tuning these trucks are a PITA. I have an appointment on Friday to have mine dyno tuned. The shop that I am using does quite a bit of work with Whipple and actually makes a good number of their programs. After that long-winded explanation, I do have to say, the low-end running issue I am having trouble with gets ironed out on Friday, but the Whipple Supercharger is an amazing product and makes amazing power. I will know more of exactly how much power it is making on Friday. I can say that 20 mph to 110 mph happens before you know it, and with a wide-open throttle, you will be forced into your seat. I will update and answer any questions.

I finally was able to install the supercharger about three weeks ago, but had a few issues, so I did not want to post until I worked them out. I am starting my write up today, will post in the next day or so.

Is there a certain diode to use?

Sorry for the delay everyone, I will write up my install this weekend on another new thread.

Well, after plenty of researching and procrastinating, I purchased a Whipple Supercharger and started to install it late today, should have it complete by tomorrow, or Sunday. I am not in a hurry, just making sure that everything is installed correctly. I have a 2017 Chevy 2500hd High Country 6.0l that I am installing it in.
