Dropping the Exhaust

[Skyrine-Dave]

Hey Guys,

Would dropping the exhaust off the back off the turbo cause the car to run differently and affect the tune?

I am thinking it would as there is no back pressure... better scavenging off the ports. I ask this cuz i gotta drive my car down the road to the exhaust shop to fit my dump to the exhuast.

Also... Fitting larger injectors. If i throw in a set of 460cc's upgrading from the 270cc stockos, the car will be running quite rich? true?

Cheers

Dave

ok drove it without the exhaust... runs like a pig, wouldnt idle or maintain a real stable idle.

Loud as all hell.... spool noise just echoes thru the streets.

Dump was attached to exhaust and idles normally and drives 'ok' up to 3000rpm. I think i can say now that the larger injectors are just overfueling it and prevents it from even getting on boost properly.

Bigger injectors will *definitely* overfuel with the stock ECU, even moreso than if putting in a bigger fuel pump. You should at the very least get a piggyback ECU to fix it (S-AFC or E-manage or the like)
