The second alternative will be more efficient ?

That is the golden question. I wish I had a definative answer. Since you do have access to MAP tuning devices (that can do either MAP or MAF) I would focus your efforts on the MAP values first. I believe that is how the PSI kit works (or worked?).

My guess is that what you will find is that the stock fuel tables only go up to the stock PSI range (13/14 psi) and then a generic formula kicks in.

I would also put a resistor on the IAT1 value (our IAT sensor is included in our MAF sensor) to scale down the temp. This will help keep your timing up. If I knew how many ohms i would tell you, but it will take a little expermenting and a bunch of CEL's. That will help your timing big time.

Ok, I've decided that I have to start somewhere. Where I want to start, is adding a little more fuel as boost comes on. I will be ordering a wideband this coming week, before I get into it.

That said, if TC, or Wop, or anyone else, could tell me what is the BEST method to do this, both for sake of learning, cost, and complexity. I'm very handy with the tools and such, I'm a software developer, and I know how to solder, splice, cut, etc...

I'm gonna look through some past threads on the subject... any advice is appreciated..
