Well I got my Spider box yesterday for my 320d (177hp) and thought I would share my impressions.
First of all, they still sending the old pictures of mounting instructions. I´m gonna send them an email about it because I also have some other questions.
Anyway, thanx to Budgie the installations was a piece of cake. I started with a calm testdrive (after calibrating) and let the engine get warm. Then I took it up on the highway and floored it on the 4th and 5th gears. It quickly accelerated up to 200 km/h and I had to look on the speedo to realize how fast I was going.
But I had expected more. But I´m used with my second car, a Saab Aero with 300++ horsepowers and that one accelerates like an M5 400 hk from 100 km/h to 200 km/h.
Anyway, I did some acceleration timing tests before and after the box with a instrument called AP-22.
The first run was 70-110 km/h (40 mph - 70 mph) in third gear.
Before: 5,06 sec
After: 4,37 sec
The other run was 100-150km/h (60 mph - 90 mph) in fourth gear.
Before: 9,48 sec
After: 8,13 sec
And today on my way to work I had the chance to test it a bit and it felt much quicker than before. Next thing to check is the consumption
