I have a zex wet kit single port and made some runs a few years back on a forge engine with a 35 shot.
My car back then was on emb and static at 5 degrees and i use the midle fuel injector and 9 grade spark plugs. Was a good power incresment/very rapid.Obviously was never tuned proffesionaly and i had only empty two bottles of juice.
You need a new map to suit everything with a bit of retard (the amount need to figured out), a healty engine (forge preffered),new and a bit colder plugs (wich need to be checked after every run for safety ressons), a full botle and thick wallet incase something goes terrible wrong!
Zex supply 3 juice injectors and 3 fuel injectors. I used the lowest juice and the midle fuel together.(if you have an other way to short the fueling then you can use the proper one and adjust the map by your ecu).
You will need also a T to the fuel line to have fuel delivery to the kit port and a microswitch wich will enable the shot at WOT.
Have it at the back of your head that if something goes wrong could result in a banggggggggg in a matter of seconds.
