Hi

I am afraid that I do not have the luxury of a awd dyno.
Reason is that I live in Iceland and I can only tune at the track.
The track is run like a sports club so not that hard to get onto every now and then when I want to, so that is good thing.

I would like go get a comment on what could be the biggest thing that is holding my power level back.

I currently have

Engine
Built bottom end
Magnus intake manifold
stock throttle body
stock head - with kiggly springs/retainers
Jun 272 cams
Shearers GT35HTA turbo kit with a recyrc from the wastegate instead of dumping
Hallman boost controller

Fuel system
Aeromotive A1000 fuel pump
Aeromotive fuel pressure regulator
FIC 1050 injectors

Ignition
Sparktech COP ignition system
NGK BPR8ES sparkplugs

Intake / FMIC
Custom 4" intake
SBR 3.5" FMIC
Buschur 2.5" intercooler pipes

Fuel
Either 93 octane or Sunoco MaxNos (I cant get VP fuels here)

Engine management
AEM EMS

My current times are 11.267@125.9 on 93 octane running 27-28psi
And 11.025@130 on Sunoco MaxNos (116 octane) running 40psi, I was really disappointed by the power I made on this setup and tune and I did play a bit with the timing.

The parts that I mostly leaning toward upgrading are the SBR FMIC, Head and throttle body, I would probably see the most gains from a ported head .. or so I would think but that is the most expensive as well, so maybe it would be smart to upgrade 2-3 other items before I do the headwork.

Anyone with experience please chime in if you would.

regards
Gudmundur
