For the pricetag of the COBB TCM alone, i'd just spend the extra money and get a full Goosetune which includes the TCM

Livernois tune is laughablei can tell ya what’s NOT worth it- getting a tune that DOESNT touch the TCM like the one cobb initially sold ya (especially a vehicle w/ a ******** 10 speed) if the truck is granny shifting & skipping gears, dropping the shift torque limits etc the extra power isn’t going to equate to nearly as significant improvement in real world performance/acceleration, hence why they never provided before/after 1/4 mile times
since you go ripped off by cobb initially if it were me instead of letting em rip ya off again by selling ya the other 1/2 a tune @ full tune price maybe try another vendor/tuner.....

I am running Cobb ECM/TCM stage 1 on 93 octane and dropped 1.1 mile per gallon average. Granted, I think I drive more aggressively now - it’s simply more fun to drive. I am currently averaging 15.1, mostly city.hows the highway MPG at 1000-1200? Are you getting more or less then stock
I'm running goosetuned stage 1 ecm and tcm. Gas mileage hasn't changed for highway driving. I get 14.8 before and after, granted I live in a pretty mountainous area say keeping the load down is pretty tough.hows the highway MPG at 1000-1200? Are you getting more or less then stock
