Calling All R34 Gt-t Owners!

[nuffsaid]

Hi all

This is following on from a post I made here http://www.skylinesaustralia.com/forums/in...howtopic=184222

Car is a R34 GTT with the following power mods - split dump, hiflow cat, and fujitsubo catback, apexi pod, stock SMIC

The EVC was tuned very nicely on the dyno and so I thought I was all set. 9.5psi on the low setting 11psi on the high setting. I dont want to go any higher.

Problem is I am getting a peak reading of about 11.7psi on very cold nights when I floor 1st or 2nd gear. (on LOW setting)

In 3rd gear, Ill get about 10.9psi max.

I didnt try 4th gear on the street.

Has anyone who has mildly modded their R34 experienced similar issues with boost peaking a bit higher than what was set?

And do you find ha the boost tapers off because of perhaps a spark, fuel, intercooler, or stock ECU issue when running 11psi?

See attached dyno sheet (red line is low setting, blue line is high setting)

Thanks all
