“Definitely recommend Big Turtle Tuning. I was hesitant at first because I haven’t seen too many GX’s with the OTT tune. The GX feels like it came to back to life. Almost as if I don’t have the extra weight on my rig like I do..”

Pete K.

“…best money I’ve spent on my truck so far! Best mod I’ve done so far. I was considering re-gearing the rig to get better torque and help with the gear hunting. The tune did both of those and was a fraction of the cost it would have been. Best decision I’ve made for this rig!”

Jeff C.

“Do not even question this tune for a second. This is absolutely the best Toyota tune ever created. Big turtle tuning, thank you. Thank you, thank you. It is worth every penny.”

“Big turtle is no bs! Awesome guys and they treat u right. The power diff is very noticeable & not doggy on low end anymore. Don’t mess w/ the others and chance not being happy; get ahold of these guys. They don’t advertise mileage but my experience already I’m over a 1/4 tank where I’m usually on the light by now and I’ve been getting on it w/ the extra power.”

Randy D.

“This is the real deal. Big Turtle did my 22 4Runner TRD OFFROAD and it was a night and day difference. It's like my rigs balls had finally dropped! I seem to remember there was a slight increase in MPG. But once I felt the power, it was like... "It's alive!!!”

M. Hardin.

“I wish I’d tuned my truck back in 2019 when I bought it. The difference is remarkable. Need to schedule my wife’s 4Runner for a tune next time you’re in Post Falls!”
