So true! A mate of mine has a performance shop and has to retune a lot of commodores, there is a local guy that does road tunes on LS and they all end up at my mates getting them fixed, he calls them the drag tune there all the same tune and running extremely fat. Make sure you get professionals to work on your vehicles guys, cheers for this spot on 👌🏼

Absolutely mate! The same thing goes with petrol cars too. Do it right the first time - get it properly custom dyno tuned! This particular customer paid the same price for his "load & go" tune file that we charge for a full custom dyno tune as well. Crazy!

@@UltimateDieselTuning it is crazy that people do it but they are just misinformed and tricked into these carpark tunes. Out of curiosity I have a 2013 200 series, what sort of power do you normally see with an exhaust and tune?

Horsepower. Foot Pounds. Screw metric
