running no lambda standard map,
 

Will i have any issues with this?? since fitting the 3" downpipe i havent been using a 02 sensor due to it being sqaushed i have one coming, will this cause any probs on the standard map other than drinking more fuel!!

You'll be running rich most likely, safer than lean but not ideal!

I have a spare OE sensor from the headers on my bugeye if you're at Goodwood I could pop it over?

Shouldn't be a problem as the ecu target fuelling will get it close to ideal

Cheers for replys chaps! thanks nick would love to make godwood but got to save all my pennys for next month, ive got a sensor coming hopfully monday thought id better ask and be safe than sorry lol
