I'm curently looking at buying a SCT X3 tuner. And I'm wondering what 3 custom tunes i should get. I tow a trailer about every weekend. I know one will be 87 economy tune.

 

I would go with a 93 tune, it is all that I use.

 

87 economy, 93 performance, 87 towing

 

how much of a difference would I see between the 93 performance and a 87 performance

 

there is a difference but IMO its not huge, i rarely ever run my 93 perf tune. it stays in 87 performance for everything from towing to off road.

 

If you don't mind me asking who are you getting your SCT X3 from? Im also in the market but can't make up my mind on where to buy one.

 

u can get one anywhere but i'd say just get it from rogue performance and have fred make you the tunes

 

X2

 

Thanks guys. His website was a little weird but I guess thats why they say don't judge a book by its cover. Time to drop him a line (I love tax refund day).

 

yeah he does great work. Just shoot him an email and he'll help you out

I always use the 93 tune in my truck. But damn it loves gas when I do that haha.

But good choice on the getting an X3. With custom tunes that's the only good tuner for our trucks IMO. The store bought ones just don't do the same as they would on like 2fiddy or something.

 

even the ones u get for a "2fiddy" are not worth the money.... same deal... go custom there and get oh so much more....

back to topic-

so you all with tuner, what kind of mpg increase did you see in the economy. also is there a tune for a 92-93 octane? im not a fan of 87 just from the deposits it leaves in a motor( please god no flame). also anyone running an auto trans, did it help much?

 

^flame

 

Also with the X3 can't you firm up the shifts if you have a auto?

 

You can vary the shift firmness a little through the programmer but most of it is set up in the tune. I hated the auto transmission in my truck until I got the tuner, it is much more drivable and efficient now. I am not sure how much mpg increase comes from the trans itself.

 

yes you can

 

I have noticed no mpg change. If anything it is a little worse sometimes. But I can for sure tell the truck is more powerful and shifts sooo much better compared to stock. Do y'all think if I changed from the 93 tune to my 87 I could possibly get a few more miles out of a tank of gas?

 

What would you say about getting a 87 towing tune or would it just be best to run the performance tune when towing?

 

you can get a torque tune if you want but you can also do just fine with a performance tune. you can get 3 different custom tunes on an X3

 

Yeah i know i can get 3 tunes. Right now i know I'm getting 87 economy, 87 performance tune but not sure what to do for the last one?

 

id go with those two and 93 as the thrid

 

Yeah so your saying just a 93 performance tune? And it would have to be 91 we dont have 93 here.

 

yeah i'd just do that but its completely up to you and what you want or need. 91 is fine. you can get tunes made from as low as 85 up to 93 octane, just specify what octane you want/need

 

Do you think a 85 economy tune be pretty close to a 87 economy tune?

 

really don't know. id be lying if i told ya lol

I'd email a tuning place about this stuff, they know it in and out
