Fg "restrictor Ring"

[Pazzo]

Don't think lights will as its after the cat.

[Drift Mitch]

Took mine out yesterday, took about 5min. Easy job. I'm actually surprised with the difference it's made with low throttle driving, feels a lot better, and feels like it's pulling harder and getting onto boost better.

[Kroozin]

How did u get urs out?

[Drift Mitch]

Just a long nose die grinder mate.

[EFSIX]

wouldn't it be easier and more power efficient to run an after market cat? (if the car does need a tune or retune?)

also from what ive gotten from the psots is that the euro4 started in april/may 2010 onwards or is it july?

[Kroozin]

I dont think a tune was req. going by what one of the guys said with back to back testing on the dyno + if you know someone with a die grinder this mod costs $0.

[ratter]

was boost error logged on the dyno to know what really was going on?

[Pazzo]

So taking the ring out Ratter you think will affect boost on a stock car? even after the cat

[ratter]

with a stock tune the ecu will try to correct it back to the required level, but can only do so far
