MY 93 WRX import, Decat,optimax + millers.MBC fitted couple months ago

The problem,
Car accelerates great if done from first through gears
great spool up just running std boost 0.9.
But Car is very flat when you try to accelerate whilst moving e.g 3-4 gears
like a stutter or as though miss firing, Not all time one day ok, next not.

I checked the plugs and they had orange deposits of octane booster but clean
off with cloth. 2 of 4 (new coil packs) were Stuck(needed freeing to allow
spring to move up and down).

Could it be that the plugs are goosed even after 2000 miles?
or that I got duff new coil packs.

Is the boost controler sticking or something or only works properly when
you give it hard acceleration?

Any help appreciated.

What plug gaps? should be 0.7mm

The coil packs are new? if not time to replace them perhaps.

All 4 packs are new, but as I say 2 of them are sticking up inside
when checked. The copper cap inside doesn't come down freely
and needs some damp start to get them moving.

If it were the glugs i would suspect loosing spark when booting hard
but it's the opposite.

The plugs are 6B's put in the pro sport which have been ok
until recently.

I think maybe the booster has knackered them again?

The booster does coat things but I would hope they would last longer than 2000miles.

Car back to best this morning, very strange.

I may take the boost controler apart at weekend and check all
pipe conections for leaks etc.

I would have thought that if it were the plugs or packs they wouldn't
work one day then not the next?

This scoob is like a box of chocolates, you never know what your gonna get!!
