AM ... Is custom tune needed after having new 3.73 installed today!
Well... My baby pony is going under the knife this morning! Alright! So it isn't s knife! It's worse! It's Mr. Wrench and he's not coming alone! He"ll be bringing his Companion Mr. Flange! I think I had better stop because l could have so much fun with the Ring and Pinion and a Master Bearing kit.
Seriously! Today I'm having the 3.31 gears removed and FRPP 3.73 installed and as I mention I purchased Motive Master Bearing Kit.
Here's my question. Do I need to have any type of recalibration done due to the new gears? I have my SCT/SF3 Tuner with tunes for life that was purchased as a combo with the JLT CAI? I just realized that this may have to be done after installing the new gears today. If yes, is it possible for AM to write new tune today? Someone please tell me what I need to do or what to say?
Here's something else. The mechanic that is installing them will not do the tune! I have to! YIKES! ! Talk to me before l talk myself into a full blown panic attack!
