Im running a forged Td05-16g Glanza - Had it at 286.5 from Tuning Devlopments but looking at freeing up the power. Had new manifold, exhaust, bigger injectors and water meth which should see me over 300 safely when i next map it... I was running 440's and they were nearly on full cycle so upgrading to 550+ is pretty much a must ... I love it, think its a wicked setup - lots of fun but quite laggy, but when you do come on boost, all hell breaks loose ...
