Does anyone know the real reason for the delay of the release of whipple supercharger for 2019 GMC AT4 6.2? Also has anyone heard when available? I can not get straight answers.
I have been told a few different things like this Sierra has new computer from 2018. The air filter is on opposite side than last design so the redesign is taking longer.
I ordered my AT4 2 weeks ago and wanted to time it to have it all to install when truck arrives. Not looking good atm.
Any info helps. Thanks!
