I have a 300k km driven LCR 2005 with BAM and it should make 225hp. Generally it works well:
* Acceleration is smooth (no hesitation), torque starts from ~3krpm
* Smooth idle
* Goes thru emission test
* No engine light, limp mode or fault codes that I know of
* Boost goes to target value 0.8bar upon full acceleration, goes even to 1.0bar with current setting
But:
* My air-vent fitted OBD computer shows max 170..180hp based on air intake values
* It also feels like more 150hp than 200hp of real power
* Engine eats some oil, must add some at least once in 10k km oil change period
* Smokes a bit more than I would expect
* Exhaust tip + surroundings get black and smudgy pretty fast
What i have done/checked:
* Fixed loose wastegate flap, this affected occasional chirping sound and improved boost a little. Turbo now sounds healthy and seems to spin with lower rpm.
* Tightened waste gate actuator so that boost pressure reaches target
* Unplugged and blocked the air line from dump/recirc valve to test that boost does not exit there
* New plugs
* New air filter
* Cleaned MAF with crc air sensor cleaning spray with negligible effect
What I might try next:
* Make sure the SW is correct and someone has not put a 180hp sw in it. Should the max 0.8bar boost request indicate something on this?
* Measure compression (does someone know the good range for BAM?)
* Check timing (any tips?)
* Send injectors to a test
Any theories or advice?
