I never understand all the retuning that goes on. Plot your course, get it installed and then bring it all together with a tune. Had the new pulleys not come along, I would never have needed a new tune...
Lets be honest, this tune on a stock SRT-6 won't put anyone into 11 seconds. This isn't the point!
From personal experience with my stock SRT-6, after the tune I only calculated a slight increase in my 0-60, and really didn't get any increase when it comes to "seat of the pants" dyno. (I'm doubting a 38hp gain)
On the other hand, What I am noticing is a smoother power band, faster response to accelerator pedal input, and more predictable gear changes.
This has greatly inproved the drivability of the vehicle and as a stand alone "modification" is well worth the money.
Also, don't forget you have life time tune's, so now with any bolt-on's you can easily maximize your gains at no additional cost.
Overall Verdict, this is a very good first purchase for any stock SRT-6. (can't speak for N/A)
