well i figher it would cost about the same when the headers get installed so what you all think would be the best mod

 

I picked up 35 RWHP from an MTI tune on my VHO.

 

You wont go wrong with a Nelson tune!! That was the best mod i ever did. With the mods you have and a Nelson tune you'll be in the 14's with no problems.

 

If you plan on gettin a tune down the road go with the headers first.But if you are only gettin one or the other get the tune.

 

Get the tune, then if you get the headers down the road Allen will update you for free. Allen is the man, a great guy and will help you in any way possible. I am on my third tune,with the fourth on the way for my new heads. I am in Jersey so I just purchased HP so I can get the tune dead on with his help since he is in Texas. Allen rocks!

 

Go for the tune first if you are going with a nelson tune. It will make it a completely different truck, and like mattrem said, nelson will give you free updates later if you want.

I'd go with the tune.

 

I consider my Nelson tune the foundation. I can build anything on top of that because I can get re-tuned for whatever I do next. Quite handy IMO.

 

One more nelson vote, mine runs great

 

14.60 @ 93.74 on my MTI tune, intake mods and Flo-Pro HD muffler. Get the tune. Nelson and MTI are both excellent to deal with.
