Default 02 WRX going stage 2!

Hey so I have read quite a bit and from what I have read I should be fine but want input from others before I press the button.

I have an 02 WRX currently has on:
- SPT Intake
- invidia catless up pipe
- N1 cat back

I have a V2 AP on the way along with a catless down pipe. So I should be able to go straight to stage 2 after down pipe is installed. Or will going stage 1 before be safer? I have read the newer maps are good with the SPT intake as I guess the old ones weren't? Will be doing data logging and is it better to drive granny style for a little bit before doing so? And if I just go with one of their Stage 2 Maps should I go with the stock or cobb one? Thanks in advance!

you dont really need an intake (stock is rated for around 300hp) but you can run a full exhaust without a tune and it wont hurt your car. you will obviously not be getting the full hp potential, so its still a good idea for a tune. And a cobb stage 2 tune will work fine.

I am waiting on the DP to go Stage 2 with the Accessport. I went Stage 1 the other day and while data logging I wasn't seeing anything out of the ordinary.

I approve the SPT Intake with Cobbs Stage 1 map for sure!

Will see how the results are once Stage 2 later this week!

Follow the map notes EXACTLY.

Approve in what way? Have you data logged?

If you are running an SPT intake, you really should be getting a protune for it. Luckily the 02/03 have enough leeway to allow it.

Stage 1- Stock or intake plus tune
Stage 2- Downpipe (plus or minus intake) plus tune

Follow map notes EXACTLY.

Been logging and my A/F hasn't gone past -3 with the SPT intake. I'm keeping to logging to be sure it stays that way. A protune is in my future

Should be alright with ots map till u do bigger things to your car. It would be a waste of money for a protune with just an intake and exhaust. Save ur money and run stage 2 ots map

Yup put in the DP and go stage 2. Night and day. Until you, running around with Stage 1will be ok. Takes 10mins, reduces lag probably 300rpms and holds boost to redline instead of tapering to wastegate like the stock tune does after 5500rpms.

IMO, tactrix and opensource is way better than cobb but that's just me. I've owned both and even the OTS opensource maps are more powerful than cobbs OTS. Dyno day with just UP/DP stock OS OTS I was doing 220whp/218wtq on my 2.0. Where others where doing 200-210whp protuned and Cobb. Stock STI where doing 220whp...some slightly less.
