8bit... I finished installing my MBC this eve, went for a drive and after stopping and adjusting it half a dozen times I have managed to set it up so the turbo no longer flutters/spikes to 27/28psi. Its now hitting a max of 25psi (when loading up in 4th) but I will trim it back ever so slightly to 24psi I think.

Car feels just as quick and smooth :)

You said above you will fit a boost gauge before deciding on a MBC. Well so you know I didnt go for the £90 Forge unos MBC (despite have many forge products!) because I found this MBC on ebay which has great reviews and like the Forge one is a ball and spring type and I got it for £18 delivered so I thought worth a go! http://www.ebay.co.uk/itm/MANUAL-BO...arts_Vehicles_CarParts_SM&hash=item33590a0d2d just thought I would mention it! :)

Nice one, cheers J@mes :) I hadn't decided what MBC to go for, just the only one I knew of was the Forge Unos. I'll do some more logs and get a boost gauge before I buy any MBC tho. Thanks for the link ;)
