My first question is does anyone have either upgrade on a SRT6?
Does the HP increase justify the cost (IYO)?
What are some pros and cons relating to these upgrades?
Thanks for some insight! 
Here's a good right up. Steve's SRT smokes the road.

Can't go wrong with Renntech, expensive (they quoted me $3,300) so If they have come down I will give them another call.
Best name, best engineering - if you can afford it. I am sure with the performance gains you can always justify it.
