Cannot Raise Boost!

[chalky]

Hear are my mods...(r32 RB20)

FMIC, Full 3" Exhaust. 3" dump/front pipe. HKS POD, GFB BOV, HKS cam gears, and timing advanced a tad.

Hears my prob...

Ive raised boost up to 10psi, tried pushing it a tad further for sum fun ( knowing i could cause damage) and once boost reaches its full potential the car seems to stutter (Misfire) but if i gradually build up the boost it doesnt seem to have this problem?

Any ideas?

regap your plugs to 0.8mm

[chalky]

ok. how do i do this?

[tridentt150v]

take out your spark plugs, use a feeler gauge set [buy a set for around $15, can get bigger better sets for more], and squeeze your plug gap down to 0.80mm, it will be set to 1.0-1.1mm std.

Ask someone to show you how it's done, once your shown its easy, annoy your lawnmower shop or something [anything with a sparkplug], with a plug spanner, feeler gauges, and a spanner set for other bits and pieces, you'd get it done inside an hour or so.

so all im pretty much doing is screwing plug in a bit further?

[BLSTIC]

No. Looking at the spark plug there's a bit that comes up from the centre of the plug to the end (the end that screws in). About a millimeter away from the end of that is a tab bent over that comes from the side. Making that gap shorter is this name of the game today. Don't let them touch, coils don't like it if they do.

ok so setting this gap will do what exactly?

[chalky]

and if this method still doesnt work then any other ideas?

[Jmaac]

making the gap samller makes the spark stronger and stops it from 'blowing out' under boost

check coilpacks

My bet is that you have a standard ECU which will retard timing and run rich when you try and push boost past 10psi.

You need an aftermarket computer or a Apexi SAFC or similar at the very least.

Was thinking the same thing

[chalky]

yeh ive got the standard ecu but my tuner advanced my timing a fair bit.

He suggests turning it back a little, in which could resolve my problem?
