My car is running a spitronics standalone and its a South African made ecu, Aem is a far better ecu but i would say to get the vvti disabled and see if that helps the hks cams are perfect for it.
I have wondered this since day once because it breaks right there. However I have unplugged the solenoid and didn't seem to make a difference. Does your tuner know AEM as well? Would like to reach out to him if you have his information. I know that dynosaur performance is reputable place but the vvti was always my concerning watching them when dynoed it. Also before this I drove for months on another tune and didn't have an issue.

Why did you go with M8280 and not Kinugawa or Mamba Tek? Also I know it is more laggy than a CT15B, so why did you choose not to rebuild/upgrade? My turbo is bad and I'm looking for options but little time to wait for rebuild.

Hello, I posted in here a couple of years ago and since then i have fitted my 1jz gte vvti into my is200 and have had it running for about a year now. I am still looking into the Tomei 8280, As you have been running it for a while would you recommend it? are the cams still breaking?
