#21 of 115 RE: 540 Upgrade by anf by snagiel Jul 31, 2002 (12:44 pm)
A "cold-air" intake will add 10-15 hp (and a lot of noise), a freer-flowing exhaust might add a similar increase (and more noise), and then you can get into all sorts of upgrades like lighter pistons, cams, valve stems, etc., but I think the price would outweight the benefits there. More involved work (i.e. $5000+) would be adding a supercharger, which can yield another 100 ponies or more (see http://www.jimmy540i.com/). If I were you, I'd wait for the next 5-series, which will reportedly offer a 3 liter, twin-turbo inline-6 with 380 hp. That would be sweet, assuming the lag is minimal.

I am the new owner of a 89 525i and I am so disappointed with the "get up" of the car. I was told this car is "gut less". It only has 187K on the clock and the engine runs fine. The problem is the car just doesn't have any "ZIP" and I think having to rev. the car from a stationary position burns the fuel more than I would like. Would changing the chip , I think "Dinan" is the word mentioned, have an impact on my car's zip. Would it be compatible on my 89.I am also considering changing the gear box (manual) to a newer used one , say 93/94.Is this possible. Any information on how I can improve this will be highly appreciated.   Thanks

Your main problem is the engine; You might try a Conforti chip- www.turnermotorsport.com . The 91-up cars had the superior M50 engine. I'd suggest that you ditch the thing and find a nice 535i; the "Big Six" makes a world of difference.
#24 of 115 Activating TV on Front Monitor by slane4 Aug 14, 2002 (7:44 am)
Just bought '97 540i with Nav System. Front screen only. Manual says TV is deactivated there for safety reasons. Someone said I can activate it to get TV up front. Anyone know how to so this?

#27 of 115 Thanks Snagiel! by slane4 Aug 17, 2002 (4:38 am)
Hey, it worked!! Very cool....thanks. Any ideas on how to improve reception or number of channels?
#28 of 115 RE: Improving reception by slane4 by snagiel Aug 17, 2002 (11:58 am)
Um, no. I don't even have the nav, I just forwarded a thread which I thought would help. How 'bout driving to the tallest mountain in the area?

Unfortunately I must live in a dump called Cincinnati and there are no mountains within 500 miles of this toilet!! Ha, ha. Thank you for your assist. SL
#30 of 115 Premium Trim by jpc14 Aug 22, 2002 (4:53 pm)
I am considering purchasing a 98 528 that has the sport package and some additional features such as heated seats. I love the car (great milage, etc.), but the only bummer is that I really like the woodgrain Premium trim vs the Sport trim. Has anyone replaced the trim before or know if it can be done? Is it doable without costing a fortune?
