Let your mapper decide when he's got it on the Rolling road!

all depends where it starts to detonate i'd say!

why do you say that? mfi can easily and safely fuel to 18 psi!!

just quoting wot i was told by jamie at jamsport mate

14psi on a 1.6 and 14psi on a 1.9 aren't the same thing.


I think 1 bar will be about your limit, from what i've seen. You'll either start to run lean or if you have a great metering head, you'll be close to the limit of your rods (if the turbo flows enough).

1 bar is 14.5 psi

well my heavily modded 1.8 runs 18 psi with no bother at all and has been doin so for over 4 years now!!
