Can i squeeze a few more hp out of this?

Lordhowe · 04-05-2006, 06:50 PM

In my previous post i have a few plots of my 03 wrx on a dynojet. The boost is right around 15.5 psi and the AF is pretty rich as you can see.

I was wondering if i should spend another 300 on a wideband to better tune this myself?

In other words, if i lean our my mixture, let say high 10's and or low 11's across the board and up the boost to 17 psi, what type of power should i expect to see?

thank you

really isn't worth it in my opinion, i took my wrx through a lot of upgrades, even fmic tuned on race gas w/ stock turbo, if i had it to do over again i'd either have left it stock or immediately put a bigger turbo on (stopped with a vf30/fmic, got a sti)

Uncle Scotty, i will do it just for that. But would you think 20 more hp is feasible with leaner mixer and stepping up the boost?
