OTS Stg2 with only DP?
I'm still a noob, so if this is the wrong forum, please move it. Other than that, here it goes. I just finished installing a Stromung downpipe onto my 02 WRX. After that I (upon reading here that it would be *ok*) upgraded my ECU to Cobb Stage 2, 93 Octane 1.30 with my Access Port.
I drove around town and it felt like a dog, AP Live boost said I wasn't getting over 8psi.. Drove back to the house, did a ECU reset and that seemed to go away, atleast it got 13psi the next trip out.
So I started searching on here and found the wastegate actuator rod mod, and tightened that up 2 full turns after running datalogs of the car with ECUEdit. After I was satisfied the car was getting target boost 15.8psi (+/- .5) I started looking at the datalogs. My concern is the knock correction values under boost.
Here's is the engine mod list
Everything else looks decent to me. It's no protune, but once I get more $$$ I'll get the rest of the toys (TMIC, CBE, pnp Headers, pnp Monster TD05)
Here is a before and after according to my GTech Pro. Runs were done before and after, about the same fuel level and same temp on the same road. I didn't launch hard either time (I like my clutch!).
I'm not sure why the graph is so spiky, it doesn't feel like it surges or anything, I think it might be the pitch factor setting is to low.
So what's everybody think? Is it normal to get 30 HP from a downpipe and reflash?
