Ok had the tuner for about two weeks now and here's my opinion.
I bought this new off a guy who got it then sold the truck shortly after never installing it.
I put the regular tune on it and was amazed by the difference it made in throttle response. The performance test said that I was running a 15.5 quarter with just the tuner and muffler swap. I ran this tune for about a week to burn all the old 87 octane fuel out of the tank. The best fuel I can get here in Oklahoma is 91 octane so I went ahead and put on the performance tune. Kinda disappointed. I went from roasting tires to nothing really. Not a loss of power. It's there. Trust me. Just not at take off. And my time went from 15.5 to 15.9. Now idk if that's cause I am still tinkering with the shift points or if it is cause I have only done a muffler swap and nothing else but it was a little shocking. I put the regular back on it today and it still doesn't want to burn them anymore. Idk I'll have to play with it more. I am very happy with it though. Word from the wise: don't put on the performance tune and expect a mileage gain. It won't happen. Like I said the power is there and your mileage will suffer from it. Now I do plan on putting on a Vararam Air Grabber and a Moes Performance 85mm throttle body. But that's it. I think once those are on my power loss issue will be solved. Also I think the gas here in Oklahoma isn't rated right and that you should run higher than the recommended octane for the tune. Like I'm running "91" for the regular I think you should run "93" or better for the performance if you have access to it. Just my 2 cents. Overall though very pleased. I have tuned and retuned at least 6 times in the past two weeks and it's such a breeze. Anyone can do it. And it only takes about ten minutes if you know what you want to set everything to. I would absolutely recommend this for some one who want a tune with the ability to change shift points and rev limiters with out the fine tuning things that the diablo offers, that just the everyday driver looking for more power won't use.
Figured I should update this now since it's been about two months in. Biggest news is the tuner is up for sale!!! After the latest update it started making the motor ping. Which we all know is indicative of pre-ignition or pre-spark. Both are very bad on a motor and what makes this worse is that I was running 91 octane ethanol free gas on their regular(moderate) tune!! Didn't even change the shift points!! Turned off the MDS system and raised the speed limiter and that's it. Not happy. Especially after I went ahead and did the pillar mount and everything. As I said before the problem never started until bully dog released the newest update for it. I think it's 18.104.22.168. Once I did that my excitement and enjoyment that initially came from this product very quickly turned to me begin terrified to even try to run the truck. As I said its up for sale. I have even been on the phone with bully dog and they took over my computer and switched out some file that fixed the problem for a day the it started again. Four times!!! Sorry bully dog but this guy is done with it!!
Like I said I am completely unsatisfied with it at this point. I'm done messing with it and calling the help line. I'm just gonna sell it and take the money and put on the Vararam Air Grabber and be done messing with it. Maybe I'll try another brand at some point. I think that if they had sent me the right Diablosport tuner the first time that I would have been happy with that and the ability to change my settings so that this problem could be resolved on my end without so much frustration. But since I got the wrong one the first time and this one is giving me hell since the update I think I'm just done with them for a little bit. If you know of another one I could try please share for the future and those others that have read this and want more info on it!! As far as myself though I'm gonna take a break lol. Too much stress for this guy!!!
My t1000 came in the mail this weekend. Was a bit of a fight to update with widows 8, and Diablo's customer support isn't open on weekends, but I was done installing it in about two hours. I messed around with it the rest of the day lol. My 0-60 was 6.54, what is everyone else getting?
Also how do the custom tunes do as far as 0-60 and 1/4 mile times?
I think my 0-60 was around that. Maybe a little slower but not too bad. The fastest quarter I did 15.9 I believe. And that was one time right after I got it. After that I never could clear 16's again. That Ping was just too scary for me!! I'd rather not shoot a piston out of a brand new truck. My truck is 3 years old with less than 40,000 there's no reason it should make those noises. And I know it was the tuner because when i would pull the tune off it wouldn't do it anymore.
