02-05 WRX owners that have reflashed to Stg 1

I wanted to ask any of the 02-05 2.0L WRX owners who have reflashed there car to stg 1 how they liked it?

What were the differences you felt from the 2.0L?

Did you like the upgradeed reflash?

Thanks everyone

Big difference is it doesn't buck as much and the low end response is much sooner. Peak doesn't actually change much but the response from 2000-3000 RPMs is dramatically improved. It's much smoother running as well.

Stage 1 on either WRX or STI, be it the 2.0 or the 2.5,is a big improvement of the factory map. Base maps are still "safe" and can be tweeked more, but still better than stock.

Stage 1 is a nice/mild improvement. But, you get used to it quick and will want Stage 2 which is a lot better than stock.

thinking back to when I did that...the engine idled smoother and there was a noticeable (but not great) increase in usable power. (mosc described it well) I certainly liked it at the time.

Stroked and stoked!

I currently run the Cobb AP Stage 1, and after installing it (which is very easy, just connect the wires, plug it in, and then select your program) I felt a good amount more of low end torque/power...

It really made a big difference in driveability. It's so much easier to zip off the stoplight, or merge in traffic. The lag is virtually eliminated b/c of the low end torque.

I had a problem with hesitation throughout the RPM range. It was a lot smoother with Stage 1. Of course, that made me want Stage 2. Honestly I think the Stage 1 improvement was bigger than the Stage 2.
