Okay, I'm not trying to be a buttwad here, but that goes against what I read in another thread on this. The most pertinent part is from Cardoc who is over in the Ohio forum a lot:

Ok... logic is on this.. 20 degree drop in air temp increases injector pulewidth 8%... Advance- 3% . The engine would have to first start missing and not firing to destroy a cylinder from a washout - Or a faulty injector that didn't close. We're talking about the pulsewidth.. (The milliseconds the EEC fires the injector) I have done this to many F-Body GM cars with great success and never in the last three years engine problems. To be honest Lance... the effect is only felt at WOT. Let me explain further.... - The oxygen sensors will adjust the mixture when warm.. 14.7 to 1 or approx best.. When the car goes into WOT, it disregards the O2 inputs and goes full rich depending on Engine (Coolant) and Air intake temp... Also MAF demands.

So there is no constant enrichening going on... Only at WOT... where the mixture is guaranteed to get diluted with fresh air.

Not trying to get in anyone's face here . . . just trying to get a handle on this mod. If I go to a Superchip (or equivalent) does that negate the need for this mod?
