Welcome to club Vis My coupes previous owner was a Dr. It covered about 3k miles a year in the later years so I guess it was used for mainly town work. Performance was lethargic. But, after an oil flush and change, a full service and changing the stuck open 'stat things started to get better. By exercising the upper rev range when the engine was warm it started to rev cleanly to 6k rpm. The best thing I did was to take it on a 400 mile round trip to Leeds , much of it motorway. Maybe this is why your car feels sluggish?

A good service is what they need normally plus a fuel system clean because mine felt very sluggish until giving it a good dig out. After a tank of V power it seamed like a new beast and very happy up the Rev range.

Another post tonight reminds me that the thermostat on mine was stuck open when I bought it. This made the mixture too rich and knackered performance. Basically the needle moved off the bottom only when it was properly warm, and only got to 90 in heavy traffic on a hot day, and dropped down again when on the move. What does yours do? See this post.

I have similar desires to tune my VIS. I did the full service which costed 1000€ 2 years ago (and about 20.000km), changed the thermostat which means that it needs about 3 min to warm up to 90*C and stays there fixed, cold or hot day no matter what... Also change the water temp. sensor also... The VIS delivers power over 3500 range where it has the most torque,but after I'm kinda dissapointed From 4000-6000 it does rev put it doesn't pull at all, seems like it strugling or something.. Fitted K&N box filter which didn't do any good, it maybe made it even worse.... So now I wanted to have more "power" from my VIS the first step should be exhaust and Remap from FCS? I do however have 18" ultaleggeras installed which weigh about 18kg with wheels which I think is not that much...I would swap for 16" orginal 20vt alloys but the grip on 18" is much better..... Also cleaned the MAF sensor but I didn't do much difference.....I would buy new one but I costs 100€ which is quite expensive if you consider that I might not change anything.... Still angry when the Coop doesn't pull as much as I want in high revs, it makes overtaking cars hard and risky... With my ex chiped 16VT it was much easier

the only way you're going to get more power would be a trip to see leighton at FC in bristol.
also mentioned in the post already a good service should do the trick, dont bother with cone filters, does nothing good for the vis, freeflow exhaust should open it up a little, but if you were to get it done, do everything before the map.

[/quote Something isn't right, my Vis pulls all the way to 6k and would probably go beyond but I don't. I had poor performance when it was running on four cylinders - does it sound like it's firing on five? Whip the plugs out and check for a wet plug. Also, with your big wheels, would that make the gearing higher and blunt acceleration? Mine pulls 3100 rpm at 62 mph (100 kmh).

If it workes on 4 cylindres it probably wodn't go anywhere Could be that the blunt acceleration is cause by 18", but im not sure, spark plugs all look ok. As I said until 3000-4000 it pulls ok, but afterwards.... Not so ok. I think I would probably have to change the MAF sensor, but Im afraid that won't change much.... Any recomendation for better spark plugs?

Yes I did my VIS MAF no trouble. Was an instant fix for me. I am fairly sure it uses the same as some Alfas.

The VIS engine in my bravo HGT I got a few weeks back has been tuned, got receipts for cams and map also has a stainless exhaust manifold, induction kit and a loud exhaust was running a decat too but I've removed that to put through an MOT once I've had that done I'm tempted to take it for a rolling road to see what the output is.

Have you checked the vvt solenoid is operating correctly? How do you check that? I prosume it does, because It pulls nicely in 3500rpm range...

The VIS is very prone to knock, especially with warmer weather and if the engine has excessive heat soak e.g. sat in traffic. The knock sensors can also be overly aggressive, resulting in a noticeable and inconsistent power delivery, especially in the mid to high rpms.
So yes Jack, Annie is correct that the engine will run better with a high octane fuel, in fact I would recommend it for all owners, as well as an FC remap to make the difference!! I can also say that it runs better on 100 octane fuel, I use it all the time, it's also true that the inconsistent power delivery comes with different engine temp. ...will need to change the MAF soon and remap Is the k&n box filter and sport exhaust necessary or just and option for better performance? Would it be still OK if I got my VIS chipped and use stock exhaust and k&n box filter? Will the k&N filter affect the lower range?

the panel filter didnt kill the power low down like the induction kit did and also seemed to give more up the top end than the standard filter which you would expect.
its worth while doing the filter and exhaust just before the chip so you see the complete difference in my eyes.
