last week i install a cold start injector from a saab whit a pressure switch on my car
to get it more rich than a 14.9 for 1 at WOT at 7.2psi of boost but at first i was not really
enthousiast at this idea to put a injector whit just a stupid switch to control it but it was cheaper than a mf2 or sds and i decide to try it.

here is the result:12.3 for 1 at WOT 7.2LBS OF BOOST on stock injector.
the switch is pre set at 4.5psi to inject fuel at this pressure when it begin to lean.

148.5whp and 186.1lbs of torque at the wheel on a 2200 whit stock internals.
i know it is not the fastest 2.2 but for the price of my extra fuel set up me and the guys who tune my car were really surprise of the result.


I AM RICHHHHHHHHHHHHHHHHHHHHHHHHHHH

I personally wouldn't be to thrilled with that a/f ratio. Granted it's alot better than it was, but i have seen more than one car come apart with that a/f ratio. And these were built motors and all. I tune cars for a living, and i always shoot for 11.5-11.9:1.

uh... do you have an ecotec or the 2200? you're registry is not filled out correctly...


that torque output is crazy... what else do you have? I'm looking to boost my OHV very soon... (right after I pass emissions so I have 2 years to enjoy the car boosted before worrying about inspection again)

Those numbers at 7psi are def OHV, my Ecotec put down 136 last weekend, my A/F was at 14 Im not gunna even get into it with the s/c until i hit the dyno.

thats it im kinda concerned now geez i figurec those number would be way steeper but those 2200 arent big on hp either



"dude, thats a girls car"
NOT ANY MORE!!! PSHHHTTT!!!!

What about a set of stock Z24 injectors? Might be a bit safer....
