It probably worked for you as your fuel isn't great to begin with, so it's probably performing like it would in England running 99 V Power
Exactly mate
I think that is 100% correct
Not sure if I mentioned it before but; when I had my car dyno'd before it was mapped it only made 184hp and 200ft/lb.
It's a solid car. Had 68k on the clock at the time. Very well maintained. It also had new oil, air filter, coils, spark plugs, cam follower etc. etc. before it went for mapping. So there was no good reason for it to be 16hp down on factory quoted power.
After the map it "only" made 224hp and 240ft/lb.
You would expect a similar car in the UK to be making a reliable 200hp before tuning and maybe 240-250hp with a stage 1 Map.
I think a big part of the issue with my particular car is our fuel. Once I added the octane booster the car came alive!
I reckon it's probably somewhere closer to 240hp now. Which of course is very noticeable on the butt Dyno if coming from 224hp.
My tuner is a good friend and collaborator with Niki Gower and I believe they share mapping strategies. So, as mentioned by Dan, I believe my car was crying out for octane to optimise the map installed on it.
I'll probably end up being Cheryl's best customer until some brave fuel supplier in Ireland comes back the the market with decent fuel.
Our garages now have no signs on the pump (they used to) telling you what octane you're buying.
For all I know its probably 93 or 91RON fresh off the boat from the USA
