Most people confuse lag with boost threshold.

Are the front covers the bolt on style? I think you have gt2860rs-5 and you need gt2860r-5.

Also, dragon humper why do you think lag will increase fuel economy. Regardless of boost pressure it takes a certain amount of air/fuel to accelerate a car and maintain its speed. Just because a stock gtr might be in positive boost and your car is well into vacuum doesn't matter. They both take the same amount of hp (air/fuel) to maintain speed or accerelate at the same rate.

I think what he meant to say is that with low displacement/turboed engines you have the option of not boosting (daily driving below 4000 rpm) and you therefore have better fuel economy vs a high displacement engine.

When you're not boosting it's only a 2.6L.
