Give us details on the motor, bolt-ons and tune. Running a CAT / Hi flow CAT?

 

 

Well, you should have the tune checked out & determine its level of fitness, so to speak.

Shooting flames as in "Anti Lag" looks & sounds cool, but is super hard on the turbo, exhaust mani & will likely tear up a CAT over time

Not sure if youre car has Anti Lag tuned in or if youre just referring to the 5500 stock 2-step.

 

 

If its the stock 2-step, thats why there are no flames. You need an Anti-Lag tune to produce what the English call "Pops & Bangs"

 

If you want the "flames" take a look at the BEE*R rev limiter...

 

As I understnd it, to shoot out flames, you need to retard ignition by more than -10° (depends on how long it takes for your exhaust to exit tailpipe) and any cat will clog up flows to put out flame. You need flame to keep burning until it exits tailpipe where fresh oxygen allows rich mixture to burn up extra fuel. If flame goes out before exiting tailpipe, no pop (what you are experiencing).

 

oh there's a stock 2 step? so probably just a fuel cut not spark cut

 

Oh crap, you're right. 2 step cuts fuel. Thanks for pointing that out.
