Sounds like you should weigh your priorities bud. One race with a last minute setup/tune, or wait it out and do things the right way? Is this an end of the year race or a money run? I would personally just wait and do things proper for the sake of my investment.

If you can't wait, I wouldn't push a t28 of any form past 16-18psi. Your most likely out of efficiency at that psi anyways.

Don't run more than 1.1 bar on stock turbo, stock t28.

I'll put together a map for you and then you can run the higher boost. I'm guessing you converted to MAP sensor by using a Power FC? Haltech?

PM me I might be able to help you. :picardfp:

14-15psi is max for your turbo dude... Wait it out, not worth blowing your motor for a quick race.
