Facelift Intermittent power issue.. FIXED! :)

Hi Guys,

Since fitting a Technics V4 turbo and having power drop issues straight off coming away from the rollers (car made 430whp) I've obviously been trying to nail down the issue.. Firstly replacing the APR HPFP with AutoTech internals, which seemed to improve the power delivery.. but still miles off feeling 430whp

Anyways, FINALLY found the issue! and embarrassingly.. it was all my fault!
