First off this is a Mustang Dyno not a Dynojet so figures are roughly 13-15% lower and it was a hot day yesterday and humid.
Second the car didn't feel right after install and you can tell from the first dyno run - running 9s fuel mixture - rich rich rich and power suffered.
After a more modest tune thanks to Scott from ROE and emailing back and forth we got it to mid 11s and power increased and car is much more responsive and curve more smoother. I know we can twick it more but I rather be safe than too lean.
I am not sure if the tune that comes with the system is very very conservative but I strongly suggest you dyno tune it after install.
Car is bone stock (either than supercharger) and cat and muffler delete. No other mods. 2000 ACR with 23,000 miles
Thats what I thought but I compared to data online with other mustang dyno runs and the numbers are correct. They are usually 13% in power difference lower for the Mustang. If you search online you can see this. People have tried both dynos same day and power difference are around 13% and some even up to 18% depending on the Dyno age etc.
Car runs great and Scott from ROE says numbers are good for Mustang Dyno. Curve is also nice so don't see an issue. On a side note the hood was open, I should of closed it to allow cooler air into air damn probably would be a bit higher also.
Anyone else have a roe with 5pound pulley dyno they can post on a mustang or dynojet without meth injection?
