Hesitation after augmented boost
Hi Scoobynet
My Impreza GC8 from 98 has been running stock boost (0.95bar) up until now. It runs fine - but when I raise boost to 1bar with an MBC, it starts hesitating and idling rough. Sometimes it'll cut out. If I let it sit overnight, it'll be fine the day after, until I hit 1 bar again.
It's running NGK 6 spark plugs - could this be a symptom of this plug being too hot for the new boost level, or does it sound like a totally different problem?
Current mods are:
1 bar through mbc
Downpipe with sports cat
Sports catless from dp
Simota panel filter, silicone hoses
Walbro fuel pump

No it has been running fine, and I know several people with a similar setup (no remap) on a gc8 that run fine. The old classics seem a little more forgiving.
I'd just like to have everything in order (spark plugs etc.) before a remap.

Exactly: I'll need a different ecu, hence my wish to minimize risks before this expensive operation.
Since you all advise me to just do it with the same std. spark plugs and everything, I may be overthinking the "prepping stage".
