“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.”
