Just curious, what is the max boost people have ran with this turbo. I put 60# injectors and WBO2 in just the past summer. I had 42.5# injectors. With the bigger injectors I was able to turn down the Alky ramp rate from 5.5 to 4.0. I have never a seen a single degree of knock. I will be doing my last upgrade this year, I'm getting a bigger IC. I'm sure it won't hurt. Right now, I'm 25psi of boost on a good tune. When Milan opens up this spring, I will be out there as early as I can. Making some passes with my WBO2 and Powerlogger. I will also go some reading and see what info. I can gather. I bet if I searched I TE44, I would probably find out more information.
