car has been running good untill i hit 0.8/9 bar then she cuts out so done a spark plug change today with ngk-pfr6b with gap set at 6 on imperial size and boost is getting up to 1 bar with no cut out but its idles ruff??? is the gap right? my95 wrx running Z4 ecu with mines chip td05h full decat k@n panel fillter will be going back down in a bit to open the gap to see what happens any more info would be great thanks.

 

I dont do imperial but you want a 0.6mm gap for a modified car and 0.7 for stsndard

 

The Problems you seem to be having are very similar to what I was having

I`m Running TD05 18G, 550cc Inj, Grp N Fuel Pump, Full Decat, Apexi Power FC, FMiC, HKS Induction, Apexi AVCr

Gap of 6mm is right.....Had my Type-RA Re-Mapped at Andy Forest recently, and had my Apexi AVcr Set up....My higher setting is now set @1.4bar Lower Setting @1Bar...But was advised by Andy that my plug gaps was set to wide and need to be closed to 0.6mm...

Before I had my re-map, my car idle was rough too, it would almost rev up and down by itself..... Also, it felt like a fuel cut at high boost. But since the mapping day, new plugs at 0.6mm gap, I`ve had no trouble at all.. Idles perfectly, boosts strong and no cut-out at high boost....

So, maybe a nice fresh Mapping Day To Cure All..

 

jgm here i come then....

 

re done the gaps last night and set it up to 16 on the imperial size i know this is not right but iam getting up to 1bar with no cut what-so-ever in any gear so iam happy un till i get it mapped. thanks
