I am not very knowledgeable in this area, but I am looking at a whipple supercharger kit. I know that I will have a professional install it and i know that my stock ecu will need reflashed and tuned for the upgrades... Other than that I am clueless. Will my truck support the added power as is or will I need to upgrade something else for it to be safe? If needs anything for the tranny or rear end to support the torque and stress I would like to know ahead of time. Also, I have the full k&n system, the tubing changes with the whipple kit, but will I be able to continue to use my filter or should I use the one that comes with the kit? I only ask because I spent $300 on my intake system and it would be a suck to waste it. Any help would be greatly appreciated. I have a 2005 silverado z71 for referencing parts. Thank you for your time.
