I took it on a rolling road for a power run last week and it only made 380bhp.
The car is a saph 2wd.
Any ideas what to look at to why its low on power?
Regards
Could be down to LOTS of things:
1. Intercooler not man enough, so high ACTs giving low power figures.
2. Standard head / cams still on car, so WON'T be the claimed power figure.
3. Car hasn't been mapped properly.
4. Combination of all the above.
