i was originally going to, but i ended up getting it fitted & tuned all in one. i also needed a bosch fuel pump, cos the stock one was running out of puff. i got boostworx do do mine, they did a top job. but i also heard good things about graham west too.
with that first 4000RPM right before the boost really kicks in, the computer over-richens the air-fuel ratio, not sure why, but thats why it goes all flat. i noticed my car used to back-fire a lot around those RPM, but now it rarely ever backfires
youll love the midrange difference that you get.
my favourite part was the loss of that flat spot right before the boost hits. now there is nice thottle reponse all the way through.
thanks for that info will, i didnt know the shell was only 95RON.
i didnt put much of the shell fuel in there, just enough to get me by. so today i filled it up the rest of the way with BP and its running all good now.
from what ive read the knock reading of 75 isnt too serious, but ive learnt a lesson there.
not sure about that one.
i always put BP in my car, execept i ran out last night & the BP was closed so i had to fill up with shell, starting off for the first 5 minutes i took it easy then i went up to about 4500RPM in third and got a knock reading of 75 on the PFC!!! im gonna wait till this tank runs out & im never going to put shell fuel in there again
some nice cars on that cruise
i went for a bit of a drive last night, i had to put shell fuel in my car instead of BP, it started knocking heaps bad so i had to go home
