Right......

Accelerating in fourth gear, from 2000rpm......

Boost comes on strong at 2500'ish....smooth and no Knocklink activity

At around 4000rpm there was an instantaneous flick up to the red LED and then all well again.

Normally I don't see any more than one or two LED's unless I really thrash the motor.

New, uprated fuel pump going in next week (and maybe a FPR)

Any comments?

my sti v5 had similar prob-changing the maf cured it-pops & bangs also returned-so it had probably being running lean.

Fuel pump might sort it then......maybe I'm slightly lean at the moment.......but only occasionally?

Make sense??
