Keep reading so many different things about fuel, my car is a wrx typr ra, import. As far as im aware the cars ecu or boost has not been altered, but its running an exhaust with the second cat removed and an air filter, and a dv.Im currentley using optimax and the car seems to be running fine, would like to know if i need to use an addative aswell. Also what aprox b h p will the car be running, any info will be much appreciated, cheers

Fit a knocklink just to safe.
If it starts registering det use a booster such as Millers or Nitrous Formula:thumb:

This might make me sound stupid but what is a knocklink, and where can i purchase one? cheers

There's a groupbuy on at the minute http://bbs.scoobynet.co.uk/showthread.php?t=369072.
Consist's of a Bosch microphone mounted on the engine block connected to a display.
This registers det,knocking, pinking etc via a series of LEDS.

Regarding boosters I swear by this http://www.nfeurope.com/stockists.htm :thumb:

If so do a search and they are not well regarded, IMHO NF is the mutts....:D
