Conversation Between TIZERBOY and Apostle

Hi Tizerboy ...... For some reason your message never flagged up & just seen it months on... So you've prob made up your mind and spent your monies lol.
But if you haven't - I've still got the Grimmspeed tmi but now on a 2.3 not the 2.5. It's really good and does the job for me - I'm getting 476bhp @1.65bar with a Blouch Dom 2.5XTr 8cm 'polka pickle' turbo. If I went fmi I'm sure it'll break 500 easy but it's not all about numbers but drivability. The tmi is super responsive along with the Grimmspeed boost controller and 3port boost solenoid all mapped together. Early boost and explosive performance.
I transplanted the 2.3 into a new 2016sti 3000 miles ago and it's epic - totally shocked that we got 'air' on a small hump backed bridge accelerating in 2nd gear (took off ! Lol).

Hi,, just been reading your post from back in 2013 about your grimmspeed tmic,, thinking of getting one can you tell me how they perform in the summertime heat with heat soak?
Thanks malc
