Anyone want to spill the news on the R20 revision. Whats it improving with the new info?

2003 6liter hear and this new tune works really good here best ive had so far 65 hp tune in r20 package

Good to hear.

I loaded r20 it seem to me that my mpg went down. I only see 13.6 to 13.8.For me the r19 was better. There must be someway to get better mpg

Can you provide how you did your test. These past couple days i have been testing the stock calibration in my vxbc9h2 calibration. Currently the truck is stock as for a PCM calibration and tires. I do have a CAI and 4inch Exhaust on the truck. I am getting 15.5 mpg on the stock calibration. Fuel economy is best when running between 60-70mph.
In town driving with very heavy traffic it will actually go down to the lowest i have seen 14.9mpg. For those who have mileage calculators in your trucks- the calculator actually goes by injector pulse width and miles driven. I will provide more info on what else i find out more.

So it looks like the r20 is the tune to have. Does everyone agree?

Thanks

i like the r20 myself but its only the second tune ive tryed ,also not sure if the r20 tune iam running is the same as the one on download page i send my cal id to mikel and he sent me this r 20 tune for this cal id 2003 6 liter disel anyway it seems to work good here way better fuel milage then what i was getting with 8r13 tune

Cole, not for nothing I tried to put in some custome tunes could not get it done..... and even the original tunes from the R20. I am getting 12-12.5 mpg down from 17.....lets face it this BLOWS. I have lost it and it may not be your fault but someone needs to step up and take blame. I would personally like to speak with the owner. Since the takeover I am disgusted with Diablo. I am buying a new Ford 08 and I will not be going with you all....unless something is done immediately. Diesel and gas in general is expensive help the working man out and put a fire under someones A_ _ !!!!!!! Word travels quick, reputation and having loyal customers is what keeps a business going.
