This is a good, strong tune. I highly recommend it. It definitely works with the R365 RED turbo. It will burn serious rubber so make sure you have good, wide tires. I am port injected so I run an E50-60 blend. My stock Si engine blew up really bad with much less HP so I now have a fully built motor with built oil pump. Use at your own risk but beware. Stock Si motors aren't as strong as you think. Trust me. Outstanding tune. I absoutely love it. Knock control is at a steady .49. Fuel trims are on point, etc. Thanks TSP and IMW for creating and selling this tune! This tune is badas_!
