I have got conflicting stories from Troyer... One tuner there told me I could run it on the stock pump/injectors, and so did Mike around January. I finally get ready to do the thing, call to order the pulley and the story totally changed to now that I need their one off fuel system and that is the only way it will work. I know that they know their stuff, but I feel like I'm talking more to a salesman anytime I call that shop
I myself think the stock stuff should handle it fine, but I rather be safe than sorry.
There are plenty of record holding cars running water/meth kits and have been doing it for a long time.
A set of 4.10s would be fun though, currently at 3.73 so it's not bad
