The only way you're getting more mpg than a chip tune is if you're cruising leaner than lambda 1, regardless of the management employed. I'd personally like to see the data you've amassed from the experiment you did when you swapped out the management for a good chip tune, ran it round for a few days, then back to standalone and did the same journeys at the same time/temperature/pressure/on board fuel quantity etc. It might be suitable for a pub discussion, but I'd hate to mislead people on a forum that's normally excellent in its sources of technical information and resources. Especially when

My mate knows a welder who made the entire system up in stainless - not sure what the boxes are, but there's two on there: a big round one in the tunnel and the back box in the usual mk2 place, I suspect he may have made them from scratch as my mate was talking about having to find him some exhaust box filling. It's quite quiet, certainly to the point that it doesn't give away whats under the bonnet - almost a shame really, but always worth it when disappearing on someone who really didn't expect it from a little ol' mk2.

Which one did you use out of interest? I think the manufacturer is SPA - bought on ebay. Like I said' date=' no problems so far. These were a custom set as I specifically requested 8.0:1 - so they'd bloody better not be 8.6! Can't really complain about the turn-around time for custom work - only took a week to do and another two days for delivery to my (not very local) parcel force depot over in team valley! I've not done anywhere near the mileage that you have, must be on about 3k in total, and other than boost pipes popping off every now and again, touch wood no problems. Not teaching yo

I'm no expert, but that sounds like the factory immobiliser - if it is the problem, it gives you basically two options: - find the fault as to why the immo isn't working (fitting all keys, immobiliser boxes, etc etc etc) - get the immo removed from the ECU A friend of mine sorted out the immobiliser removal from the ECU for me in exchange for an amount of money (I can't remember how much, I'll check that with him too) if you want me to find out what he did?

Doh! I never even thought of that - I'll see if I can find some spare jubbees and give that a go! I've not had a chance to speak to my man who knows these things yet unfortunately, though it might be worth giving them a ring and finding out from the horse's mouth so to speak. Are you an inline-vee turboer like myself, Bodge?

They do' date=' it's just the angle on one of the pipes doesn't quite sit right, so when under load it tries very hard to pull itself out of the silicone tube on the input to the intercooler. I'm sure it was correct when it was all measured up and fitted in the first time, but I'm buggered if I can figure out a way of making it sit correctly now. That being said, I have reseated the engine since then so I guess it may have moved around by the required amount to make it not right. Recently heard of C2... can't say I know too much about software/ECUs etc, I've got a mate who sorts all that out

Hi all, been reading for months and never posted, so here goes with numero uno as I feel I've been in a similar situation recently...
