@performancetransmission: @gregrexadams a friend wants to install this in his wifes Pontiac G8 430WHP NA with a built 6L80 Ive walked him through. @CircleDTrans Single Disc 3000~ plus converter possibly, trying to remember because of all of the drama recently trying to get back on track. He has the stock tune file currently in it and cannot achieve a 2-3 shift under WOT. My opinion is to get a data log first and fine tune before getting too agressive. The 2-3 shift issue may be because it hasn’t adapted yet on a fresh build as to why we need to see the data log. But my opinion would be not to put this tune in. Suggestions before i have an aneurism on the Dyno Tune File?? 🥃🤦‍♂️#mechanicsoftiktok #transmissionbuildersoftiktok #tunersoftiktok #hptuners #pontiac #g8 #6l80 #transmission #builtnotbought
