Daz C....blimey that's sky high, not runnin that boost but at 1.5bar on a stg3 t3, act's don't go over 40 on the hottest summer days as long as you're goin along at a fair pace (even on track) with my grs! 6 degrees advance ain't much is it....with lower act's and some more advance it'll be alot quicker lol.... when mine goes into the 50's it's noticably alot more lethargic and loses it's snappiness.
