right when i left my car at nicks it had a lumpy idle, the sound we all love, when i picked it up the exhaust was blowing REALY bad between the de-cat and middle section so you couldnt here if it was lumpy or not, today i fixed the blowing exhaust (although still blowing a small amount at the back) and it appears i have absolutely no lumpyness at all, im just wondering why this is? he did mention my lambda sensor was broken/on its way out...

ideas anyone?

probably mapped it to compensate for the cam duration, fueling etc... so smoothed out the idle... you got power figures from the work done?
