Alright got the new update in and all is good. Thanks
so much

I will give it a shot tomorrow night and let you know of the status.

Thanks

Sounds good. Do you have a time frame on possibly how long it could take? This is because I have to re-do the custom tune I have had done by Lew and the roads are gonna be way to slick for WOT tests in the next week or so.

I have a 2009 GMC sierra 1500 with 4.8L. I have been using the trinity for a few months now. I went to send my truck to GM for some repair issues so I uploaded the factory tune back in. I get my truck back and went to put the custom tune I have had done by Lew back in and as soon as I got to ...

I decided to get a custom tune done and I had sent you the funds lew to do this. I sent you an email on a question

Thanks for the help though

never mind about my tuning as I am getting you to do a custom tune for me. Sent you the funds already!!

That would make a lot of sense hahaha

I will try this and let you know tonight

I have my LTFTs adjusted by -6% on injector slope. I have read 06MonteSS forms on adjusting WOT settings by 1/2 the slope. So would I adjust all my WOT PE RPM ranges (low, mid and high) by -3 (leaner), or do I follow the DSLOGREDUX program and adjust what it tells me in there which told me +6% low ...

my next question (thank you so much for the LTFT questions), i am getting some tksr at around the 3200 rpm mark of about 5. Ive read that you add some fuel(richen) to that rpm to see if its a fuel issue. also I do get some really small blips about 1-2 but I assume those could just be a crappy road ...

ok well what about 50* F? Sry for being a little picky, but I kinda wish I bought this tuner in the summer and I would not have this issue. My values are around +1.5 at these temps and I dont know if thats right or not. I tried calling diablo sport but being on hold for over an hour and not getting ...

I am trying to adjust my LTFTs but my weather here at best is 8 to 13 Deg C. What should I tune my LTFTs to. I read several forms of people tuning between 0 to - 2 at temps of around 30 Degs C

I checked the intake air temp and it was around 13 Deg C. Also, if i adjust the injector slope, would i have to re-do the WOT PE adjustments or can I adjust the slope and thats it. If I need to go a little positive, how much do you suggest. I live in canada and at the moment the day highs are 10 and ...

I have now done a steady highway drive for about 20 minutes. After adjusting my WOT PE ranges and doing the highway drive I have noticed that my LTFT Bank 1 is now -0.15889% and my LTFT Bank 2 is now 0.
12998%. These values have changed from the previous values after performing the WOT PE ...

I need some help with the tuning and I am new to this. I have a 2009 GMC Sierra 1500 (4.8L). I have done Air Raid CAI, MagnaFlow muffler with resonator removed, Power Aid Throttle Body Spacer and of course the Diablo Trinity Programmer.

I have installed the 87 octane tune and have adjusted my tire ...
