Boost pressure with MTM Remaped ECU

[gunman]

Just got round to fitting the boost gauage and the remapped ECU that the wife got me for xmas (I know it's taken too long but I haven't been well). The car seems a lot quicker but I am only seeing about 1 bar of pressure. I would have expected about 1.4 tbh, sounds like I may have a boost leak so I have just bought a boost leak test kit from andyp.

Does this sound likely to you guys? I never had the gauge fitted with the stock ecu but I did difficulty outrunning my mates vr6 golf ( and I mean he pulled away and I only caught him at the wrong side of 3 figures).

that chipped ecu should be boosting to 1.4bar, it did on my car....

Cheers, thats what I recon'd. I think this is probably a leak somewhere as all the hoses are stock and I has a leaking injector a few months back, I have new seals here to fit but haven't got around to it yet. I may hook the stock ecu back up with the boost gauge fitted and see just what that reads out.

Very tempted to order a silicone boost hose kit for it (could sell the stock ecu to help funding:mischeif, I have the piece here for the mark h mod but guess what......I haven't got round to that yet either.

I was looking at replacing the vacum tubing on the car, has anyone replaced with silicone? What dia would these be..3 or 4mm?

I'll Drop you a PM, just ordered some 4mm hose today to relace my vacuum hoses.

You can pop round to mine sometime for a check and a chat if you like... And enjoy the state of red 80q engine in a thousand pieces if you like.

I appreciate the offer Paul. It's one I may well take you up on. Due to illness I've only been at work 3 and a half days of this year so I've got nothing done to the car at all (one good point is I've only used half a tank of petrol since 7th January).

I really think there must be an air leak, there's now and again a slight hunting (nothing like the 80q was doing mind you), if you rev it then lift off the idle takes a sec or 2 to settle. At WOT it seems to be holding 1 bar, even got 1.1 bar today (in 5th).


I may be interested in getting my name put on your samco GB list but I'll drop you a PM.

Thanks again.
