Question

Since I’ve driven it now, I can hear the exhaust sounds different when I get nearer to the rev limiter. Sounds like more air is going in/out. Is that normal?
Yes perfectly normal, you have an extra 50hp worth of air flowing through the engine.

Perfect 😅 thanks for that, thought it was my luck something would go wrong.

So.. I've attached the Dyno sheet, what do you guys think.

A couple of my friends whoa aren't Stage 1 experts have mentioned the power looks very erratic and not smooth like other ones they have seen on the 140's, but since a few of you guys have had it done, wanted to get your thoughts.

I have mentioned all this to Evolve who have said if i'm not happy with the Map they will provide a refund.

But i would rather make that decision sooner rather than later.

Did they promise you 430bhp?

Who’s to say your car on another dyno wouldn’t show 420, 425 or more.... would that suffice?

If you got a refund, what’s plan B?

I’d imagine someone who knows more might come along and say that Evolve haven’t applied such a strong smoothing factor to the graph, or something along those lines.

I did ask whether it goes above 430hp and their exact response was "yes some go more than that but we quote the lower figure"

So i'm not saying that's a promise but that would make me believe 430hp would be a minimum.

also i did ask them about the graph and they said "our dyno does not have graph smoothing like those other 2" (i showed them an example of 2 other dyno sheets from other Tuners"

Well and truly this is a first for me as I've never got any of my cars mapped so wanted to see from you guys, if this seems a bit muggy lol

Ignore the dyno chart, how does the car drive? Does it pull smoothly through the Rev range??

Definitely feels a lot smoother, noticeably nicer and the speeds just keeps climbing.

Think i'm going to just put this to bed now, just think the dyno maybe wasn't as accurate as i'd hoped.

I'm sure if you went back and asked for maximum smoothing and maximum fudge-factor you'd get a very pretty graph showing 450bhp?

I think the dyno maybe was more accurate than you'd hoped.

Your trace looks very similar to my Stage 1 BM3 tune. So you have a decent safe power level map.

Plan B - refund, go somewhere else and hopefully gain 10bhp or so...

Nah. Enjoy it!

If it drives well, then I wouldn’t worry too much about it the graph.

I went through all this, and then after the second opinion, Was sure all was well.

Here is my second opinion graph from tommy at velocity tuning.

I’m really pleased with the way the car drives, I was hoping for more like 420bhp. But at the end of the day, who really cares. 400bhp is more than enough, let alone more!

Main thing is whether it drives well or not.

400 is more than enough. Evolve offer a reputable service and much better to have a safe map than something that hits the numbers but little else in terms of engine longevity.

Congrats you are in the 400+ club now

All dyno’s vary and so many things can give false readings, some deliberate and some not. Ive used evolve before and there a really decent company to deal with. Also worth bearing in mind that a lot of tuners are using exactly the same software to map cars anyway, its just brought from someone else and flashed on your car. Chances are you’re getting pretty much the same thing from many different places, but your car will read different power on each dyno for whatever reason.
If the cars drives well and evolve say its all as it should be and healthy ect then don’t worry about what the dyno sheet says
