Hey all,
Couple of months ago, i had my car dyno'd and got around 157.3kw atw, with afr around the 11-12 mark.
Mods;
- batmbl front/dump
- xforce hiflow cat
- apexi catback
- ARC 110mm SMIC
- Standard boost - leaking to about 12.5psi~
- Splitfire coilpacks
(here is a dyno scan of 150.3kw, dont have a copy of the 157.3kw run which included a new dump/front + cat)
Had another dyno run today at Swinburn Tafe and confused about the results..
*note; when the car was on the rollers, it was vibrating real badly too, he suggested it may have not been tied down properly or something..
The differences between last dyno and this one;
- New O2 sensor
- Installed a socket into my ecu for future remapping. (Standard chip in ecu, just installed a socket and plugged standard chip back into ecu)
For the past 2 years all my dyno runs have had an AFR reading of 11-12..
Why has it dropped all the way down to 10 resulting in a large loss of power
Thanks
Patrick
