I bought my 75 Tourer (116bhp) just over a year ago with 72K on the clock.

Its been a fantastic car but always a little sluggish. I bought a tuning
box (not one of Ron's, I hadn't heard of his products then) and this
did improve things slightly but it still lacked torque.

A new fuel filter improved top end but still didn't improve the lower end.

I read Ron's 75 page and did the following :-

1/ Adjusted throttle stop downwards 2 complete turns
2/ Disconnected EGR valve

The car is now much livelier and there is a lot more low down torque. Its not quite up to Mondeo TDCi standards but its not far off and its much nicer to drive.

Thinking about the EGR valve, as I understand things, modern turbo diesels are fitted with large intercoolers to draw cool air into the combustion chambers for greater power/efficiency. Yet the EGR must be injecting hot gasses into the engine which may be impacting on this.

Anyway, a big thanks Ron for your Web page.

Hi there......do the intake mod on Rover Ron's 75 page on his website (just updated), it is a revelation!.....

Did it today and was wheelspinning out of junctions (accidentaly ofcourse) and willingly revving right through to 4,600rpm....!!!

There are some notes on this on the couple of tuning box threads on the main page.....

Hope this helps?

PS...started a fresh thread on the inlet mod as it is such an excellent and free modification.....

Thanks for that, I'll give it a try.
