Hi, I was doing some "boost testing" last night and I noticed the following readings.
1st Gear - 0.7 Bar
2nd Gear - 0.7 Bar
3rd Gear - 0.9 Bar
4th Gear - 1.1 Bar
5th Gear - 1.3 Bar :D
My car is a standard engine and turbo, with K&N panel filter and a Squadra chip.
I was testing by running the engine at 2000RPM in each of the above gears - not changing up or down to get more speed - just let it run from 2000 to 6500RPM - throttle fully open.
Then I did another test of running it fast as possible through gears 2, 3 and 4 - I did not get more than 0.7 on any - even on the longer run all the way through 3 then up to 4.
I believe its how the car is intended and not any fault, but why wouldnt it deliver the full boost that I know is possible in that gear?
EDIT - Perhaps I am answering my own question (just read the "ignition cut " thread more carefully) - maybe I get higher boost when going from slow to fast in one gear because the ECU can sense a higher load on the engine...
