Splattering Problem

[FULOCK]

Hi all,

Iv just bought myself an r34 GT-T 4Door, and i have a few concerns which i hope someone may help and shed some lite on as i dont know much about these cars yet.

Splattering problem usually starts after 3500rpm, and its so bad that I just back off sometimes, other times it comes good again after about 5000rpm and fine through to 7000rpm.

I have tried BP ultimate, Synergy98, and Optimax fuel so far - and it always does it (splatters).

And another problem which might be related, I only get a max of 320k's out of a FULL tank and thats driving like a Granny!!!! If i drive it normaly (punch it here and there) theres not much difference, i'll get about 290-300k's to a tank.

- So my question is, will a Dyno help because all I hear is that you cant really touch these computers?

- What is likely to be causing this:

coilpacks, spark plugs not gapped correctly, running too rich (maybe oxy sensor is borked??)???

The car only has a 3" exhaust cat back, and a pod filter - everything else is stock (including boost )

Thanks.
