1HDT TD05-16GL Slow to spool

[antsmith29]

Hi guys, I've installed an arashi td05-16 large on my 1HDT and it's seems awfully slow to spool, doesn't hit full boost of 19psi (I've installed a boost tee.) Till after about 2100rpm and even drops boost between 3rd and 4th which cause egts to spike up. Max egts under load on a hill are about 685 pre .
I've done injectors 3 inch exhaust and big end bearings recently. Any ideas please?

At first i was thinking Fahrenheit but your probability talking Celsius temperature measurement. you could still go a tough more if its not too smokey. Worth a boost leak and drive pressure test. Check that there is enough preload on the waste-gate or try it completely shut just for a test.

I have a boost tee, and I opened it right up, will hit well over 20 psi so surely that rules out a boost leak and wastegate leaking i would have thought. Smokey enough off boost at the moment so don't really want to add anymore

doesn't rule out wastegate, drive pressure or boost leaks. Turbo might not be a good fit for your use if everything else checks out.
