I'm wondering if I now need to stop chasing the missing 30hp at the top end, 30hp I'll rarely use? Monty is now a truly epic fast road classic with fantastic torque everywhere and pussycat town manners, he's even retained his excellent 38mpg cruising fuel economy!
He's now making 33hp more horsepower in the mid range than Stage 2 Monty, and from 4,000rpm to 6,300rpm he piles on almost 20 lbs/ft more torque than he had in the alrealy grunty Stage 2 tune. From 5,800rpm to 7,900rpm he also now holds onto his 180hp, where the horsepower in Stage 2 tune fell away sharply at 6,500rpm.
Apart from the missing 30hp at the top end the Stage 3 project worked out great, so perhaps I should leave it at that and now just get on with enjoying Monty for what he is? TBH Stage 2 Monty was already fast, but with Stage 3 Monty I'm now making a good slice more torque, I've also made a meaningful chunk more horsepower and I'm holding onto both the extra torque and horsepower for longer, over 1,000rpm longer!
Best of all, I swear he's even more flexible and nicer to drive now when I just feel like pootling about.
