What everyone is saying here is correct. RB's are a proven product and have shown to make great power improvements. Our stage 2's are similar with some differences. But use the same size compressor wheel. Stage 3 is on the road now and tuning. Should have 91 numbers next week on stage 3. Stage 2's are shipping Monday to get our initial numbers, so we should have some soon. Thanks for the question and interest.
