As some of you know I recently upgraded my intercoolers. I noticed some pretty significant turbo lag. So we pulled codes and saw that mt ECU had a pretty old version of MTM software. I figured I might as well upgrade software since I had to get a reflash. After talking to Mike at Hoppen Ad told him of upgrades I plan on doing he suggested I step up to stage 4 software. So of course I did it and installed a Bosch 044 fuel pump, Bosch 5 bar regulator and colder plugs. I took some pics during the install of the pump and reg. I also found out that the NGK PFR8B plugs that I was told to get, do not exist(?). I talked to NGK north america and UK, they both said there is no such plugs. I was instead given part #BKR8EIX which I'm told is a one step colder plug just an Iridium plug. Found installing the plugs pretty simple using P3u's write up (http://www.rs6.com/showthread.php/20...ark+plug+guide). The reg. and pump were not that bad either, I would advise getting these fittings http://cgi.ebay.com/BOSCH-044-COSWOR...item2302d7d15a for the fuel pump install, I called everyone I could locally and no one had the parts. I plan doing the turbo upgrade and down pipes in the near future so until then I'll have to take a little easy on the car.
The car definitely runs a lot stronger, turbo lag is almost totally gone. The car just keeps pulling it's crazy! Hopefully this info is useful if some one is thinking of doing the same work. Here are pics of the parts I used, factory
