Surging with 275 v3

[sask08]

Anyone else experiencing surging with the 275 v3. I've been running this tune now for about 10k miles now and I can't get rid of surging around 1900 rpm. It only happens with the converter unlocked, as soon as you go over 50 mph and the converter locks up it doesn't happen. I've changed the fuel filters twice now and reloaded the tune multiple times with no difference. My truck is a job1 with about 45k miles with the S&B intake and 4" flo pro exhaust. Anyone have any ideas?

Get the 275v4. I had the same issue with my 275v3 and so did jrod on here. The 275v4 had th fix for me, plus it's a free update. Just email sales at Spartan

so i've been doing some reading and it seems that 275 v4 does not seem as strong as the v3. many people also said that about the 275 v3 and the v2. For those of you that have used both, do you think I should put up with the mild surging or get the v4 to clean it up.

Also, anyone have dyno numbers to prove this? Are there actually different hp/tq numbers for the different versions?

The v4 produces slightly more HP and more torque than the previous versions.

The power is just smoother, that is why it feels to certain people that the v is not as strong as the v2 and v3.

I guess upon doing more reading, it seems that some trucks wont learn the tranny tuning of the v4. It seems that most of these trucks are job 1 trucks as mine is. Should I be worried about this or just pull the trigger on the v4?

If you do a good learning procedure it should do fine. Mine had trouble learning because I didn't let it learn properly...I only had the tune in for 2 days, and it was all in city driving and no attempt to let it learn.

Just get the V4 and try it out, if you don't like it load your V3 back on! V4 just has a little bit longer of a learning curve I believe

Email sales@spartandieseltech.com and tell them you want to update to the 275v4, and they will ask you to do what they need you to do.
