My best mod yet - MEGA POWER !!

[dave_p]

Well, placed an order with tunit - www.tunit.co.uk for a box that goes in-line with the engine management system. It claims to increase the power from 218BHP to 260BHP (X5 3d Sport).

Got the thing this morning - very good service (took less than 3 days after placing the order).

It took about 20 minutes to install - had to remove the engine cover using a torx screwdriver, then plug a few things in - simple. Here are the pics of it installed -


I cable tied it to a metal thing sticking out from the side. Also cable tied the cable to stop any rattles.


The cable routed under the engine cover and cable tied as shown in the pic below -


Simple!!

Now for the test drive. I will post some video tomorrow when the weather is better.

The unit has 9 settings - 1(low) - 9(high)

It's comes on setting 5. My first test drive was in this setting and it felt like a different car. The throttle was more responsive, the pulling power was incresed throughout the whole range. It was quicker than ever - at least a second quicker 0-60 (if not more). But overtaking was amazing - different car all together.

I then changed the setting to number 8. WOW!! The red line appeared very quickly in the first 4 gears - the car shot to 120mph - I then slowed down. The car was amazing, think it caught a few other drivers by surprise - they must have thought 4.8???? The only thing wrong with it in this setting, however, was I could hear the engine fighting for air when I floored it - better air filter required? (I have placed an order for a K&N one - tunit advise this is fitted to experience the full potential of this product).

I have now put the setting to 6 and will leave it in this setting. The power is fantastic - it's honestly a different car - for the better. There is no more smoke at all (day or night). In fact, I can't see any smoke at all, unlike before.

I will phone the insurance company first thing tomorrow to see how much extra I need to pay for this pleasure
