Hey guys,
Asking for help, I know this is a noob topic but, I do not claim to be a mechanic. From my research I believe I need something like a bully tuner but I do not want to drop the cash if this will not fix my issue. I purchased a 2014 Ram 1500 5.7 Hemi 8sp auto 4x4 crew cab tradesman a few weeks ago. It came equipped with one of the mopar lift kits (unsure if it's the 2" or 4") the owner the dealer got it from had put Nitto Trail Grapplers Mt's 37s/12.5/20 on it. I just noticed tonight on the highway that I appeared to be flying by everyone on the road. I had the cruise set to 68, I pulled out my phone and GPS said I was doing 75. The difference it is off varies from 5-7 depending on speed. Also, I believe the tires are under-inflated to the factory 38 psi as to not set off the TPMS light , I will verify that in the morning. I'm looking to fix speedo and get the tpms light not to come on when I put the correct amount of air in it. Will a tuner fix this? If so which should I buy? Sorry for the lengthy post and for my ignorance.
