I tuned my 1066 last year to pull and put big injectors, cranked up the fuel, 3lm turbo, upgraded all trans and TA. But this year they put up the speed limit to 12 mph and I’m done messing around. I’m going to build it through the roof looking for around 600 or 700 hp. I’m not looking to lose and making sure their isn’t a tractor that will beat it. So if 700hp isn’t enough I’ll go 1000. It’s an endless bank account so I’m open for whatever
