|well it was beyond performance that just done the dyno... so they were |
telling me they had just closed it for a week to ensure its accuracy and had
repairs done, now now i know they could just be selling me a dyno run but i
would hope i could actually believe them lol
when they stuck my car in drive i think it was about 80kms as soon as they
put it in drive she went straight to 10.1, i know that an acceptable ratio
would be around the 12.0 mark
now about this advanced timing, i can already see the response lol
a possible cause could be the timing too far advanced but if i retard my
timing any further it is gutless, absolutely gutless - i'm guessing gasket
has something to do with it
if i retard my timing... in the morning when the car is cold and i need to
go somewhere i cannot drive it as it will not rev above 2000rpm and
basically sits in a limp mode until normal temperature is reached hence why
i run advanced timing :)
