    Question 1/16th mod hp????

    I recently bought a clean 02 rex wagon which had the 1/16th mod already on it. Ive driven other wrx's without this mod and they are jumpier in acceleration(weaker in first).This mod seems to hold boost longer and earlier in 1rst and second gear. Its does something positive to driveability and the car seems stronger.Ive read dozens on posts ( pro and con)on the subject of this mod.What I want to know does anyone have any idea how many hp vs torque it adds?Just curious.....

    Why back to stock??, I dont know if mine felt faster but the acceleration did feel to be smoother and maybe as a result,...harder, my car always had a jerky acceleration that was felt during 1/2-3/4 throttle in first and second. I was told the jerkiness was a result of the wastegate trying to dump extra boost.
    Its all fun and games till someone loses an eye....

    When I had this, I would get a slight boost spike (approx 1psi) and it would settle back to normal boost. I don't think that it affected my ultimate hp, but it did seem to build boost quicker.
