Flames....I need more flames :)

Ok my 05 990 SD has akros with a tuneecu remap. At around 3k on deceleration I get a few pops and very very rarely when its dark I get a small flame.

My question is, can I slightly increase or decrease fuel trim at a specific point to possibly give a bit extra fuel to make more flames?

Cheers

Throw the akra map back on it. Make sure your SAS is on and voila!

Yeh ive got the akra map on it already. There are two available and I'm tried both.
I get pops at around 3k off throttle but I want flames

You could mess with the fuel via TuneECU but personally I wouldn't do it and it wont do it with the SAS removed.
Or you could just go down this road.

Haaa that would be cool.
I'm gonna have a little mess around with tune Ecu. Just a little extra fuel on deceleration may do it.

Sas is on. No other mods just akros.
Was gonna open up air box but thinking that will give opposite results I'm looking for regards air/fuel ratios.
