It's worth it. Having the extra boost lowered my EGTs by 200 degrees with the EZ on.Deke said:I bought my EZ used from a guy at DTR. It did not come with the elbow. I have seen some adjustable elbows on eBay for around $30. Do you think its worth the money if I want to stay in the "safe" range of 30 - 35 psi?....I would only be gaining 8 - 13 psi.
