I'm Awesome
Hello
My truck is NA4 which means above 8500 gvw emissions. The manual says it has a lower compression ratio than trucks with emissions below 8500.
What’s the reason for decreasing the compression ratio?
My engine is probably not the original one, suppose it’s the lower emissions- can it run ok with the stock ecu?
