hi all.
i wish to thank you all , i used to drive my car with 1.2 bar steady boost and 1.4 over boost without a care in the world and now thanks to all of you guys ( you know who you are ) telling me my car is going to go kaboom i am affraid to put the pedal to the metal.
i have decided to get an apexi afc to take care of fueling problems. i am now looking for a method to check my air fuel ratio so i can tune the bloody thing.
i can get one of the following:
1. lambda link. 100 aud
2. air fuel gauge- appexi,greddy,hks 200-300 $ u.s.
3 motec lambda meter. dont know how much yet.
any advice ( except lowering boost or getting a link )
would be greatly appreciated
