Iv had this turbo for about 8 months now. Ran it on 10 psi last year and made 613 rw and ran 10.3x @130. Upgraded to fic 1000s and decided to turn it up. Made 693 on 15 psi on a lean pull. Richened it up to mid 11s and made 655ish. But only ran 10.21 @131. Seems like it's about out of steam, engine is a 221 cam only lq9, 4l80e, s60 rear and weighs 3800 lbs with me in it.
