I own a 1995 740IL and I just installed a K&N filter and I about to install Denso iridiums Plugs. Next, I have a choice in engine performance upgrade:
Dinan offers an engine program "chip" that delivers 15 hp / 18 ft tq. for $200.00
Dinan also offers a transmission program "Chip" to adjust shift points for $100.00
Although JET Chips offer a computer software upgarade where I have to send the CPU in and have it reprogrammed. It delivers 19 hp / 21 ft tq. for $300.00
The most I will spend is $500.00. What do you recomend? Has anyone out there ever tried the JET Chip on a Bimmer??? Do you know of other companies? Please help me make the right choice.....
