Installed the TVT injectors (Thanks, Anthony). Only had one problem, one o-ring had a thin spot and leaked like crazy, so I had to use an o-ring off the stock injector. BIG injectors, like the ones I used to use on the racing Audi rally cars in the 80's.........

TVT instructions say you don't need to use the clips, but I recommend you do -- getting the fuel rail back in with the substantially larger diameter and slightly longer new injectors, it helps to have them secure in the rail I think.

Also, use the bleed valve on the fuel rail (carefully, don't spray yourself and everything else with fuel) and it will start instantly and run fine right off the bat.

As I already have an ECU tune from InMotion, plus the slightly higher flow Mercedes V8 airbox & K+N's, and the Magnaflow, I do notice a change -- not much down low (but maybe a little better throttle response???), but it definitely pulls smoothly and strongly all the way to redline now. Can't wait to get it on the track...........
