One thing that was different is that some trucks has surging problems with V2. My dually surged anytime I ran above 68mph in any kind of weather. Most people only had surging problems during the cold weather. Some are also saying that they thought V2 was a little faster....

I went back to the V2 now and I really dont find a differnece in power, its deffinately different in shifting but I feel to say the V3 seems to run better through the gears.. its so hard to tell without having two trucks but these are my thoughts

V2
Louder at idle
Way dirtier - smokes way more
shifts seem firmer
starts terrible in the cold
Seems to spool up slower off the line
Surges at 2200 rpm


V3
When you "let off" the throttle seems to really bob your head forward especially on cruise
Smokes less
Less boost
Lower EGT's
starts great in the cold (-20c was the coldest I had it in not plugged)
Surges at 1700 rpm, but less than the V2
Shifts better

I have been running it for almost a week and will go back to the V3 tommorrow. I really dont like the "let off" of the V3, but I guess you cant have everything

Maybe different trucks and different intake/exhaust combos offer different results.

V2.
I feel it's far superior in low end throttle response and spool up.
I find the shifting to be way too harsh.
I notice higher boost numbers.
I find it 2-3 mpg better.
Smokes a little more.
Totally different sound at idle.

V3
Mushy pedal feel, very lazy off the line, and that'e enough to make me switch back to the V2.
Much smoother, refined overall tune. I would probably prefer this tune if throttle response wasn't something so important to me.
The only problem, and it's a big one to me, is the "hit your head on the dash" fuel cut off when you lift at highway speed.

Since we know that the idle rail pressure of the V2 is pushed to the max, is there any downside or potential harm being done to the injectors running this kind of pressure?

100% agree with the above, exactly how I would describe things....the mpg gain with the V2 is enough for me...well also the fact that the raw un adulterated power off idle is nice...

Is there any way to know what version I have? I received mine in mid Febuary. I would like the V2 based on people have said about it, but Ive riden in sledneck57 truck (I believe he has V3) and liked the EGT's floating around 1400deg under full throttle. With the 250 V1 I could peg the pyro. Scary.

You cant get the V2 anymore. I asked Nutty that on the Spartan forums.

You dont want the V2... I just went back to the V3 and I swear its faster... way lower boost and egt's also.. the shifts seems way better also

maybe its me, my truck or where I live but other than the sound and the "let off" the V3 in MY OPINION is better.... :thumbsup just my 2 cents

one last thing to add.... the V2 DOES NOT like the cold... even in 5-10C it still wont run as well.... as for starting in anything -10c or less is scary... or at least compared to the V3

I beg to differ.....and most agree, the V2 275 tune is faster, and more aggressive....however I never had any surge problems down here that I dealt with so I can understand liking the V3 better if the truck was in cold weather

Yeah I swapped back to the v2 a few days ago. My v3 would leave black marks, but not go crazy spinning the tires...V2 blows the tires up

I will be switching back to V2 now that it is warmer out. The T.C. lockup on my truck is a lot different on V3 and I really don't care for that. I think that is what contributes to the "throwing out the anchor feel" when you let of the pedal while cruising or turning off the cruise. I was pulling a trailer this weekend and when I turned the cruise off to get onto the off ramp I about ate my windshield.

I have the V2. When you rode in my truck it was the V2. I don't have the V3 cause I kinda figured it would be less rank and from what Rob and Wade have told me it is way different and not as fast. I'm gonna stick with the V2 this summer and in the fall I will save the V2 and update to the V3 cause of what Hollywood said... V2 doesn't like cold starts.

Yes, I wish I had my 275V2 on my SD card at dyno day last Thursday so I could have put it in to see the difference between what my truck put down with the 275V3. I was not very happy at all with the number and am on the hunt for the problem. Especially after I put in my 250 tune and came up with the same number. I suspect a partially plugged fuel filter, but am happy that Reid put down the big number for the day. :thumbsup
