Should I get the87 or 89 towing

 

89 towing will give you the most towing capability. How much are you towing? A truck that is near or at max has the trans hunt by dropping down to 3rd gear. Just get an 89 tow tune and put in 91 or 93 octane and tow away.

 

I'm not sure but it may. I have the LiveWire and it does.

 

I would get a tow tune for the type of fuel you want to run. In Iowa, our most common gasoline is 89 octane and contains 10% ethanol. If you want to run premium (91 or 93) I would tell VMP you want a 91 or 93 octane tow tune. You need to run the type of fuel your tune is set for.

 

Should be running 89 in a 89 tune for best performance.

 

Tuners usually carry 3 different tunes and if the owner wants to change then the fuel is there alredy.

 

But running 89 on a 87 tune is a waste of money and less performance,I'm aware tuners can gave several tunes loaded on them.

 

Nobody likes jj at Wms???? Everything that I have read and talked to him about he is the man!

 

I write my own tunes so I am running E85 now. Cheap race gas.

 

has anyone else here ever used WMS? Website isn't very good but he has some good info on a lightning site.

 

Do you already have a programmer? If not you get three custom tunes. If you're ordering one I would just go with the 87 octane or 93 octane.

 

love my VMP tunes

 

Ordered my x3 and vmp tunes last night n I'm *******ing stoked to get them running!!! 4.6l 3v with k&n / flowmaster. Will update here when flashed

 

I ordered a SCT X3 from 5 Star and 3 custom tunes back last fall. I was only interested in the 89 perf/tow tune, but came up with 2 others to complete the package. I noticed very little difference. I was mostly wanting to achieve better throttle response from a dead stop, and maybe some less awkward shift points. I notice no difference in throttle from a stop and the shifting was goofier than stock, seemed to downshift going up hill, which then required a heavier foot to throwing it back into higher gear. I didn't like it at all. I returned to stock and have been waiting on one custom tune (87 perf) from Troyer since Oct 25. It is very frustruating, but I hear it's worth the wait. If you're going to spend 400+ on the tune and flasher, make sure you get the best custom tune you can. I'll let you know if it's any better when I get it, hopefully within another month or I'm going to go nuts!!!!
