Real life example = ME.

I specifically asked my insurance company about:

1) blanking EGR

2) removing DPF

Both were not allowed, indeed I could not even pay an increased premium to get either of them covered.

The use of an official Fiat EGR restriction plate was however perfectly acceptable and covered.

I also have good experience of negotiating vehicle modifications when I was doing motor sport in my then Uno SX.

Insurance companies can differ on what they will or will not allow. The only way to ensure you are actually covered for any modifications is to ask. Failure to do so could result in severe consequences.

In my own experience I found that the restrictor plate improved matters for me with respect to EGR valve clogging. There was no noticeable performance effects and with respect to the emissions I can't say as NOX is not measured, however the CO and particulate measurements showed no real change when looking back at annual MOT test results.

I once asked my insurance company about legal speeding...guess what they told me...
Since than I never exeed the maximum speedlimit...
(Well....maybe it's just coincidence that I always end up driving the far right lane on the motorways, when visiting your great country in my chiped, blanked and dpf removed Afa GT jtd....).

To put your own requirements on this please provide evidence that there is no difference between 1 and 4 holes in a restrictor plate. Why do you think Fiat designed it with 4 holes rather than 1? Even with laser cutting or stamping 4 holes cost more to make. Are you an expert on flow dynamics or had any training or experience in the field? Remember with closed loop EGR control (the type that generally causes the MIL to come on) the total amount of exhusr gas added does not change when a restrictor plate is fitted. The only thing that changes is the EGR valve opens further and the gas path / velocity changes.
Your prejudice against EGR does not change the laws of physics or fluid dynamics. Orifice plates and jet mixing are common applications. Try http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19950017970.pdf for some light reading.

Moderators should be aware that their forum could have the odd mad petrol head, fragile new driver or professionals. The forum members deserve the most accurate advice possible and should be applauded for providing it. I applaud G8RPI for cutting through the Egr debate.

The moderators should not take pride in pointless argument.

With due respect what you do and how you do it is your personal decision and exercise of your own free will. You right, your decision your responsibility.

Here in the UK to modify a car without disclosure to your insurer is deemed in law to be a "risk modifier" in that you are potentially exposing one's insurer to a higher risk (in THEIR eyes not yours) than you have contracted with them. Risk modifiers are expensive HiFi systems, fancy racing seats, goo fast stripes NON of which affect the cars performance but do, for example, make the car more desirable to theft, joy riding etc.

I'll say no more on this but it would have been morally wrong of me to not point out to any person modifying their vehicles from production standard that they should also get their insurer's consent.

If nobody can not see and understand this and just want to poo poo it then fine. All I ask is that you don't crash into me or anybody else. Please crash into a Police car and tell the cops how you have modified your car and not informed your insurance company.

I guess could ask the Forum owner to remove your moderator authority on the grounds that you appear to be sanctioning/condoning illegal insurance fraud in the UK but I'm not that petty.

I'll say no more or respond any further.

Well, we may dump the "Tuning" section on this Forum as well.
According to some "know it all, been there, done that etc." folks here, even inflating tires to more than factory specs, may be illegal...

:devil:
