  1. 2015+ STI Discussion
    New to the forum and would like some advice for going stage 2. Im unfortunately in Cali and these regulations are not pleasant. I've done some readings and have talked to Drunkman(anthony) and he said that even with the new GESi downpipes, theirs a chance that CEL codes will pop up. I don't...
  2. General Subaru Discussions
    I have a 2006 STi with 36,000 original miles. It has an original Cobb catted downpipe and was tuned on the stage 2 91 oct v111 map via a V2 accessport. The accessport was plugged into a computer yesterday, and it updated all of the maps from v111 to v300, which removes support for downpipes. My...

    I'm looking into getting a fresh tune for my car however I no longer have the parts to make it emissions friendly (previous owner deleted air pump), I'm planning to go catless/tgv delete for track duty and the car was previously tuned on an Accessport. I know Tactrix/RomRaider are an option but...

    So, this post intention is to share as many opinions as possible. I own a 15 STi currently in the process of hitting 600+whp, rotated turbo, closed deck and build heads, the whole 9 yards. Originally the car supposed to be tuned with ECUtek but it turns out they also moved with greenspeed...

    Requesting assistance in finding a reputable alignment & tuning shop. I have had my engine rebuild & tuned by Six Star Motor Sports. Just looking to see if I can find a place closer. Thanks everyone for your help. I have a 2006 Sti with stage 2 tune. I didn't go too crazy as it is my daily driver.
  7. ECU Tuning & Performance Electronics
    Hi everyone, I recently upgraded the stock turbo to Garrett GTX3071R and added all supporting mods on, including turbo back exhaust, cold air intake, fuel injector, fuel pump, turbo inlet, 3 port boost solenoid. However, when I picked up the car, it feels completely different from when it's...

    I have a v2 access port for my 2009 wrx and I have maps on it for stage 2+ sf intake, I want to be able to use my maps but I need a way to tune out the codes I get from a secondary air pump delete. I can not find any way to have the codes tuned out while also having my cobb access port maps...

  10. 2.5 Liter/Litre Factory Motor
    Thought it would be best to ask this here. So, soon I will be running Tomei EL Headers paired with a Tomei catless downpipe and a Tomei Expreme Ti cat back. Going to have all the Cobb Stage 2 stuff for a 2017 sti. I was really wondering if I could run the OTS stage 2 tune from cobb or if i...

    Hello all, pardon my ignorance or lack of proper post placement. Car is completely stock aside from Group N transmission mount, shifter bushings, and rear diff carrier bushings. My AP is currently installed only as a monitor, using the Stage 0 v400 Cobb OTS tune. I'm just looking for some...
