kat if you are hitting 1400 in up to level 3 you will see over 1500 in level 5 , you should take kurt up on that offer of switching to the 14cm housing , it may also take care of some of that traction problem you are having .
briar , good point , it is possible that the inlet did alot of the cooling of my EGT problem , but i do know i can now eclispe 100 mph and just be seeing 1400 where with my stock turbo i was at 1500 on a 0-60 blast and i know it went higher than that by the speed the needle went to 1500 , like as fast as the speedo went to 60 .
