Hi all,
Ive got a vauxhall corsa C 1.4 SRI , its got the Z14XE engine.
I have got a K&N air filter , ecotek valve, and full powerflow exhaust. the exhaust only has one rear silencer and i still have my cat.
Problem being is that when i got the exhaust it had a centre silence , which i have recently had removed. the car now really drinks fuel , im not talking a bit more im talking 50 miles for £10 , and thats driving sensibly.
can anyone think of a reason for this ? and would chipping the car help, like having the fueling set up properly ?
cheers

could be your fuel management, but thats just a guess. try disconecting the battery for an hour and resetting the ecu

To be honest it drank fuel when i got it , for standard it only did 275 miles for £30 Quid , now its gettin worse. im going to thrash it a bit tonight then i will report on my progress. if it keeps up i will have to get it chipped then set up properly on the rolling road , see if that helps. it does have a hard life being a rally slag 
cheers for the help all.

Alot depends on how/where you drive. If you only do short trips it kills the fuel consumption, compared to longer journeys. Also driving styles affect how much fuel you use. Not neccesarily thrashing the car, but full throttling it makes a big difference to part throttling it.

would be good to see if people have exhauts and air filters etc to see if they effect fuel economy
