Quick question about backfiring.

[mazdasp33d]

my mod list consist of

full corksport exhaust
cpe nano and inlet
cobb ap running a v103 stage 2 + sf 93

my a/fs are like 14.7 or 8 at idle about 29 cruising and wot at 12 or 13
my fuel psi is around 430 at idle and over 1600 at wot

i havent hit boost over 21psi

i back fire time to time, and dont know if i shoot flames but is it because im too rich right? being lean is what causes engine problems correct?

8 at idle seems like super rich to me, 13 is a little lean for these engines at WOT.

Assuming you have the stock BPV because it wasn't in your mods list, I would check all of your hoses.

could be the Nano intake...there are a few people experiencing issues with it when running OTS cobb maps...

so even if it reaches 14.8 at idle it super rich? and what numbers should i see at WOT
