Ok
Just an update but I'm still chasing this popping when cold.
Took it to a local shop and he wanted me to remove all aftermarket bs like Adj. waistgate and andial fuel enrichment. Adj waistgate I did remove but the frequency valve is andial...pricey still there.
But as I understand it the frequency valve does its job after warm up.
He also found a bad waistgate, cv boots, front brakes and rotors, steering rack rebuild and column bushing..arrgh.
I just completed all of the above and installed a plx afr meter. sooooo........
Cold
At idle afr's are 12.5
If i lightly accelerate..16-18 and pops
Cruising 2500-4000 15-16
Under boost 11-12.5
Again, after a 4-5 min warm up all popping stops but I feel like the car isn't quite right.
Still fast but not exciting.
Any suggestions???
