19th Aug 12 Hello Andrew, Thank you for arranging the next day delivery for me , the tuning box was with me by 11am. I had the unit installed in about two hours, took my time to clean the egr valve as well ( it gets full of suit ). I had the box set to +2 ,drove for a bit and then got it to MAX. setting and everything is OK. The car drives so much better! It has more “jump” to it now. I do have a boost gauge installed so can say that the BOOST went up from 1.3bar to 1.6-1.7bar on the max.setting. Very impressed with the quality of the tuning box! There is one adjustment to the instruction that i would recommend to introduce for my type of engine: you should take four bolts from the top of the egr valve and remove the top compartment and then remove another two bolts that are facing the cooling radiator and are parallel to the ground and remove the egr valve, it does show the valve being removed on the picture but does not tell you to do it in description. It is impossable to get to the wires if you do not remove the egr in whole. Thanks again it was a pleasure doing business with you! Regards, Pavel Garmas.
