Get rid of the O2 sensor it's rubbish, also it doesn't give you 20BHP, and get rid of the petrol chip, they're both a waste of space mate!
To be honest there's no real cheap way of getting power out of this engine without going forced induction etc - this isn't a Golf TDI where you can drop a 400 quid chip in and get another 40BHP unfortunately..
If you can stretch to 1.5-2 grand then pick up a supercharger, will take you into the 200bhp mark, slightly more with the exhaust...
Westside.....
:D
SO that the O2 things CRAP ? cool i understand !!! so wer would i have 2 go 2 get supercharger ?
and wot the differance btw a supercharger and a turbo ? is one like 0-60 and the turbo top end ?
THANKS you ur help mate !!!
