Hi from down under, I have a conversion into my Nissan Patrol out of a 2009 GMC Sierra and have had it running for over 5 great years now. In that time I have used a few different tunes from the conversion company and tried a couple of local made ones, I can get plenty of power (probably in the 500 RWHP range) and some lower tunes hardly blow any soot but still go ok. However I hardly see any good fuel consumption, in your numbers I average around 13.8 mpg mixed driving and not nailing it over the top. Never see anything up around the 20's I read of in your bigger rigs..
I weigh in about 3.1 Tonnes, run Gt 4094 turbo, lift pump, no pollution gear, 4" Ex and 5" inlet all custom piping of course. Std injectors and only one showing high balance rate of +4.5 others around 0 to 1. Runs sweet on any dsp setting. Any tips or ideas out there ? Other conversions appear to get much better economy on similar set ups but maybe there is something in my Engine that causing high fuel use. MAF is around 80 at idle and 250 at 100K, diff ratio sees about 1690 rpm at cruise speed on my set up.
Could it just be injectors ?? thanks
