What is the latest tune # for a GM ?
I tried to update it, it's been a long time since it was done.
it says it is up to date. doesn't seem right to me.
I have not used it in many years due to gas prices.
My I-1000 is for my 2010 Colorado V8, will it also
work on earlier I4 and I5 Colorado's ? or ...

not enough power to go fast enough for road speed
to shift into 6th with those big tires

Go adj settings, timing in there

thanks, going to try it Fri. night

when i modify the tune does it change right away or do i have to drive it for a while ?
I want to be able to change fuel and timing at the track between runs.

there is a fuel sensor in the fuel line that tells the PCM what amount of E85 is running
thru it and the PCM makes the adj to the eng for it. also diff pump and injectors.

i had the same thing last year, it's a painful thing and takes a while to heal
from the surgery, wishing you well Lew.

can i fine tune/adj my dyno tune at the track using the adj stock setting on my I-Tune 1000 ?
i know i can do the TCM but how about the ECM ? timing and fuel ?

Diablo Lew mite be able to help you out with your tune, check with him.

when i install your Diablo tune does it raise the shift points and increase trans shifting ?
it really hits way to hard at WOT when it shifts, sounds and feels like a sledgehammer in the trans.

I think you can change over in the settings section

I do have a wideband gauge in my truck to work with. just trying to get a half ass tune for now,
to damm hot to get a dyno tune. it would be a waste of money and would have to be retuned
later on.

I recently installed a cam and headers and dual 2.5 exh. that's why i asked.
going on a dyno when the weather is better

give them some time, they will get it for you.
