Aproximate gains from the following..
I thought I would ask in here to see what everyone thought.
on a N/A 3800 with the following, what could be expected?
-------------------------------------------
List 1: (most interested in this mod list)
ZZP 2.5" Downpipe w/ high flow cat
Front Power Log
Tune (should I bother with this?)
-----------------------------------------------
List 2: (less interested in this list, but just throwing it out there to get input/opinions)
All of above plus later on adding:
ER ratio Rocker arms to those,
what should I expect for performance gains for each list?
IF I did list 2, would it be better to tune AFTER I add the rockers rather than getting a tune when doing list 1 or will it not matter?
Obviously the overall powerband would imnprove from both lists I would assume, and not just max hp and tq, which really max numbers don't mean as much as the gains over the whole power band to me.
Will just the first list of mods make a good change in the car'* quickness/feel/response etc..or is it not going to do much without the rockers? If I decide to do these mods it would be the downpipe and power log first with a tune (unless doing the tune after rockers would result in a better outcome) and if I am happy with that drive it that way..and POSSIBLY later down the road add the rockers.
That is like $400-450 worth of mods for list 1 (with tune, 300-350 without tune if bought parts new) is it even worth spending my time on or money on?
About $700-750 for list 2 bought new.. again worth my time or money?
Just trying to do some things to make the car a bit quicker, more responsive, and more fun to drive without doing too serious of mods
Thanks guys.

Not a whole lot, maybe a little pick up in the high RPM'* but not much, if you modified your runners in your intake you might pick some more noticeable high rpm power up.

All of above plus later on adding:
ER ratio Rocker arms to those,
ER Rocker will give noticeable power to your ride, with the above mods the effect will be better.
As for a tune, even bone stock the factory tune can be improved, but I mean an actual tune, not an off the shelf reprogram.

Skip the downpipe. Expecially if it'* from ZZP.
Your stock exhaust is better than a W body wihch is very restrictive. ZZP caters to W bodies and they haven't done much research on them. Do further forum research about how Plogs like to crack and if you get one, have it welded before you put it on the car. I'm in on the ER rockers.
The tune to do you much good should come from either Intense or a custom tune. Custom would be preferred.
