I have a MY98 UK Impreza and the only mods are Magnex BB, Magnex Centre Section, K&N Filter and Boost Gauge. I will probably fit a downpipe in the near future though.

However as I live in Ireland and SUL is very hard to come by I run the car all the time on NUL.

Would a Dawes device be OK to to use on the car even though its using NUL? What would be considered to be a 'safe' level of boost for my car?

Thanks in advance

Gavin :)

if you do mess around with boost it would be a good idea to use a good quality octane booster and get a knockink and air/fuel ratio guage to.

better to be safe than sorry!
