Here is his response, love how he is using the overhead!
a company in colorado is manufacturing the injectors. i'm still doing some tests on the vehicle that's getting 34mpg.. i've monitored the fuel consomption with a scanner and reset the mpg meter numerous times, but we haven't ran out of fuel and haven't made it to the gas station yet to get 'real' fuel consumption. These injectors were origanally made for horse power, not fuel economy. if that's all your looking for give me a couple more days before purchasing the injectors.. other mod's done to get 34 mpg? intake manifold elbow, programmer, 4 inch exhaust, air filter, egr delete, egr cooler delete, cylinder head fuel return system.. let me know if you have any more questions.
