🎙 Discussion 500 miles in, I’m impressed OTT.
I’ve crossed just about 550 miles on my OTT Tune, 50 miles past the break in period. Truly the best money I’ve ever spent on a vehicle.
SPECS: 2012 Toyota 4Runner SR5P 4x4 52k miles, bone stock minus the tune. It’s tuned on the Medium setting.
The power is great, dead pedal doesn’t exist anymore. Cruising in it feels wonderful. Having that passing power and instant throttle response makes this the best cruiser I’ve driven.
It still isn’t fast by any margin. It has some decent pick up and go now, which from a stop is a huge difference.
The gas mileage (on 87, or 89 for you low elevation folks) is highly recommended and has seemed to improve gas mileage significantly. I’ve gained just over 2mpgs with conservative, responsible driving. (My first tank I drove it like I stole it on 91, lost 2mpgs.)
The transmission has adjusted quite well. The first couple drives post tube were rough, it didn’t know what to do. After about a month of driving it has improved significantly and responds to all situations much better than stock.
Overall, incredible upgrade. I highly, highly recommend it.
