Hey guys after some advice if I may! Recently fitted a wepr top mount kit and a freshly rebuilt TF035. Long story short it's much laggier than it should be. I've had the wastegate off, lapped the seal in, checked all intercooler pipes etc. it boosts up to 0.9 bar as it should be seems to take forever to get there. Penny washer is definitely clamped shut. No obvious boost leaks- checked all pipe work and wastegate. Any ideas on what to check next would be much appreciated! Goes very well on boost but should be spoiling much earlier, don't see full boost until around 4000rpm ish? Cheers!
