Will I get good HP gains with intake/cat-back upgrades and a stg 1 tune?
Or to get good gains (more than 10 hp) I need to get the header for sure?

Personally I thought the gains with Stage1 were excellent. Header+Stage2 will definitely yield notably more, but I wasn't disappointed in the stg1. It's not ALL about the peak power gained. The drivability improvement I got out of the reflash made a night and day difference on the car, even just cruising around town. Rev it out? Huge difference.

I'd jump on the stage1 as soon as possible. When you get a header down the road, it's a free bump to stage2. Winning.
