just had a full retune.... (not a cleanup, full delete and start fresh)

car has:

hks 2835 pro s

greddy rb26 ex cam gear

3" exhaust

hybrid gt fmic

nismo 555cc injectors

nismo fuel pump

z32 afm

splitfires

bcpr7es @ 0.8

pod in box with cai

power fc

fc datalogit

blitz dsbc spec s

car made 280rwkw on BP ultimate 98 and 320 on united e85

very happy with the results as it's a very safe tune.... pulled 2 deg timing out of the top end and only lost 5kw, fixed all the cruise and idle issues, cleaned up a boost spike and got the car running absolutely perfectly.

my thanx again go out to trent & cat @ status tuning, who always go well out of their way to make sure my car is perfect!

all graphs are in sae correction mode so the results are the same as dyno dynamics in shoot 6

Has someone got a reference dyno sheet of a stock turbo'd engine? That would be good to compare against.
