Hi all, I’m replacing my old Siemens 850cc injectors with new injector dynamics 850 cc, will I be able to drive this car to the shop for a tune or Do I need a tow? Car was fully tuned and runnning well, but due to a fuel leak In the primary injectors and fuel rail, I’m replacing them. Car has a microtech 10 lt-10s. Some info on the injectors.

Microtech runs both high and low you'll be fine drive it easy to the dyno but if in doubt just tow it.

Thank you all, I will be installing the new rail and injectors probably next weekend, I will take a short drive and see how it feels, the car will be going for a tune anyway, I got a aem methanol system for my birthday :ylsuper:

yeah, you can even run a pair of high and a pair of lows, it's one thing that microtech did right.

It was the connections in the microtech, they needed some cleaning.
