You are now my bestest pal in the whole world...and all that! After me ordering the box on the phone from you, it came well inside 24 hours and I fitted it myself after my first load at 06.00 in the dark, which is why it took about 3 minutes including tilting the cab! I have used it for one day on factory setting 5 to get used to the extra grunt the truck now has and will turn it up bit by bit. It is very noticeable that it has more power now because I can skip 3-4 gears when fully loaded changing up which is very strange (but I can get used to it!). Ill give it a go for a while playing with it and let you know by phone or computer message how I get on. Again thanks mate I think for the money it cost Im glad I didnt go for the re-map. --- Update - Received 24th February 2009: Hey Dan, Just clearing some stuff from my e-mails and found this. My truck has now done 330,000kms plus with the tunit box and is still on max power from the day I got it!! (I was told 535bhp). The engine uses no oil from service to service. How much does a 480 bhp Volvo cost? because a lad in a TARMAC 8x4 had a go with me last year and could not run with me from 40mph up until the speed limiters. Thanks lads I am still happy with my box. (driving like a **** does save fuel with the box though). All the best Mark
