Just an update:
I went with the blouch td05H-18g-7CM^2, Have all the supporting mods on the car with 750cc DW injectors.
Right now im tuning on wastegate boost (10psi) and i've rescaled the maf within 1-2% in closed loop, hit afr targets in open loop, tuned the injectors, timing curve, fuel curve, misc tables, ETC. Very nice turbo for DD IMO, spool is still great, and the pull even on 10psi is like a stage 2 stock TD04 turbo lol
Lag is very over rated. The install was smooth to, fitment was perfect. I'm a very happy blouch customer.
Now comes the boost tuning, shooting for 20psi, so i'll let you guys know how it goes.
I'm using cobb accestuner race to tune, and i have a mentor over at rom raider helping me out with some questions, (IMO the very best site to learn tuning from)
