Fuel System

[BMWNitro11]

What are your thoughts on using fuel system cleaners like STP gumout in a SHO?

Also I was having problems with my idle and power changes at constant speed so I cleaned my IAB and that fixed the idle problem but not the power surges..... any ideas?

I use occtan booster's like once a month to clean every thing out. And i run prem gas all the time!!!
