Chiptuning at Yaris II Diesel??

Hello dear Toyota municipality! Do you think Chiptuning makes sense with the Yaris II D4D? I have the following offer from bhp motorsport (Weilheim near Stuttgart): Series: 90 hp, 190 Nm, 175 Vmax, 0-100 = 10.7 sec Chipgetunt: 111 hp, 222 Nm, 180 Vmax, 0-100 = ? Costs (incl. VAT): Chiptuning (Knnfeldoptimierung durch Auslöten, da über OBD probably nicht möglich) = 489 EUR, TÜV-Guarantee = 199 EUR Warranty (over tunegarant) for 2 years or max. 100.000 km Total running power = 250 EUR === ====938 EUR total. First registration 3.11.06, annual driving performance approx. 40,000 km, of which approx. 90-95% motorway. Current mileage = 11,000 km. What experiences do you have with Chiptuning? In the event of damage, I can actually rely on the replacement insurance (here: tunegarant)? AND: The car is financed and I have to/should/should return it after the contract period (= 4 years = approx. 160,000 km) at the latest. So, what do you think: prefer the fingers davo I’m very grateful for your suggestions and advice. Tschau Chris
