Wether noticeable or not is the question and I have a turbo inlet which on stock map as been felt to greatly enhance turbo response.

Kinda annoying as I bought the Thor WiFi dongle but if I'd gotten MHD would have more options but at the time thought I'd always be going BM3 so saved fifteen dollars by getting the Thor only adapter!
Boost target doesn't affect lag. If the target is higher on one tune vs another, all other things being equal, the turbo would still spool up at the same speed in the lower revs.

MHD 2+ had very little lag imo and is much more exciting and more powerful than the stock tune (with same mods). You have a relatively large ic in the do88 - you will actually get less lag with a tune.

Mhd Stage 2+ = Bm3 stage 2
(the + with MHD indicates the tune is for cars with upgraded ic)
