without some form of fuel control(apexi safc, FMU, MSnS, AEM EMS, etc) you WILL blow up your engine.
your ecu has no way of knowing when the engine is under boost, so it will not know when to add extra fuel, thus leading to lean conditions.
strangely enough, when the engine is cold, it will add enough fuel for cold start conditions to make it limp by for a couple seconds, but it will run lean under boost after being started for a minute or so.
GET SOME SORT OF FUEL MANAGEMENT MAN!

ya, vortech FMU will be good enough...just be sure to hook it up correctly!
k8 ecu will just run a bit rich, that's all...
your welcome John!

Why don't you just wait driving the car and save up some money to get a good fuel computer, some upgraded injectors, upgraded fuelpomp and pressure regulator
You don't want to blow you engine because you went the cheap way.

There's a megasquirt bulk buy starting on probetalk soon. That would be the best route to go. Megasquirt is your friend
