Still bucking
I have been running the spartan 210 and 250 on my truck for months. The truck from day 1 with these tunes has had a bucking problem around 60-70mph.After finding out this is a common problem I started looking into it and found that tractions bars would be helpful because my truck is lifted with 37"tires. Well, I just installed my new traction bars and while it took care of all hesitation,it still bucks and I am tired of it.Has anybody that has used the Spartan and Blackmaxx had the same problems with the Blackmaxx tranny bucking?

This sounds exactly like the problem I'm having. With my SCT tune in (performance) it bucks at 110k (70mph). I took the tune out, changed my fuel filters & still bucks at the same speed.
Took it back to the dealer, tech plugged his laptop in & away we went. #2 & #6 injectors were weak. But they won't replace them under warranty because they are only in the 5% below normal range. The injectors on either side of these weak ones pick up the slack to even out the engine so it won't run rough.
This can't be normal?
With 148000k on this truck I'm running out of warranty soon and I don't really want to have to pay for a repair that should have been done under warranty.
Any thoughts? Comments?
