I installed my corsa yesterday and it sounds and looks awsome, the only problem is I can hear when it switches from 8 to 4 cylinders, is there and easy way to turn this off or do I have to get a tune. Other than that I love it.

 

Sounds good man I loved my Corsa on my 01 sounded nice at idle mean at WOT but drone free at cruise. I had the same prob when I first got my 09 it sounded terrible when it would switch from 8 to 4 mode only way I know to stop this is to get a tune.

 

Yeah it sounds real mean at WOT I just love the sound of corsa, I had it on my 06. Well I guess a tune will be next. Thanks

 

tune is the only way.. but man what a difference its gonna make... so smooth without dod.. i love my truck now...!!!

 

so i am new to putting performace parts on my truck but i am looking at getting a little more mpg........ i waant to put jba longtube headers... corsa sport side exhaust, edge programmer, kn cold air intake, air raid throttle body spacer a hotter coil new plugs and fresh delco plugs? do you guys have any input on this i am reading diffrent threads and im getting kinda confused..... ps corsa does sound bad a$$

 

skip the programer, tb spacer, and coils. stock coils seem to be fine for more power than most are making. save ur money for a custom tune from a sponsor. do a search on that. for plugs myself and many others are running ngk tr55s. you can search that too but most people run that brand in these ls motors.

 

What about the E3 spark plugs, are they a waste of money??

 

A tune will remove it, I hated how my Corsa sounded when the 4 cylinders kicks, sounded like a honda.
