Also, I got about 26mpg mixed HWY/ street driving with the power tune, and used to get about 29 MPG mixed with the Eco tune. I should get somewhere in the middle now, although, I'm being more thorough about the tune in general.

Apologies for the delay! Here are the pics for the modifications needed to the UDP:fowljesse wrote:This was my "Round tuit" to put on the underdrive pulley that I got several years ago. There are a couple things that one needs to know when installing one;
When dremelling down the lip that the UDP rubs, you need to grind it all the way down to the ribs that run perpendicular to it.
It is easier to cut it off than grind it off. Mooneggs will add pictures that will show what I mean. I feel good about the mod, and recommend it to someone who isn't looking for a great improvement, or an early mod for a mostly stock car, especially lower HP car. I have a good stereo, but it doesn't take a lot of amps, so there won't be any charging problems. Also, it doesn't seem to affect the water pump.
Your motor will run with out that back plate, but you loose out on higher end power.. You'll also have a less stable idle..kulluminati777 wrote:is that back plate needed for all pulleys? My obx pulley doesnt have one....
Really ?? I always thought it needed that info to run normally.crazycanadian wrote:Your motor will run with out that back plate, but you loose out on higher end power..

No.. The PCM uses it for high rpm (3500 -4000 and up) spark timing, and idle stability... The crank sensor in the distributor is the main input for spark control.. I played around with it a fair bit when I was having issues with my old DE..WhiteFinish wrote:Really ??

That sucks man sorry, I am in the same boat with you on that. the plus side the Euro bumper has a factory screen mesh for fronts without lights!fowljesse wrote:My car now hath a lithp. Someone hit it while it was parked, and broke off the passengers corner of the lip. I wish I could catch someone doing something like this. Well, maybe not, because I would end up in jail. I've called on a few parking lot hit and runs. Well, now I'm going to do the bumper alteration that I've been thinking about. It will be purely for aerodynamics, and will look mostly like the Euro bumper without fog light holes.
