Thanks. I am a recovering nitrous addict. I can tell you that turbos are the cure. If I had to do it ALL over again, I would have built this combo the first time around and by now I would have a 7 sec car. Unfortunately, nitrous assisted in blowing up several of my high dollar stroker motors and never went near this fast. This combo hasn't broken a sweat yet. Just been trying to gather up the needed stuff to take the next step. I'm real close now.
The stock computer had my fueling control limited to 15 psi so I had to fudge the 15 psi line to run the 19-20#'s required for an 8.9 pass. My injectors are at 95% IDC aswell. I got the new computer and have it almost all figured out. My buddy BonnarLS1 has a set of high imp 160s for me to try and Dave (our welder) made me a sweet tank. Just have to swap to the 3 bar map sensor, put it the injectors, put in the tank and fill up with E85.
If I was to design a new single PT88 kit, I would have run the charge pipe opposite to how I ran mine and offset the turbo a little more to the driver's side and a little higher. This is just to be able to run a larger filter and get a little better oil drainage.

I've already done all that and now I'm working on the modifier tables. I know that it seems that I am all over the place with this but there is a method to my madness. Because my first AEM was defective, I wanted to make sure that the bells and whistles were all working before I got in to deep. I have a good bit of experience tuning and so far none of my problems have been tuning related. They have all been configuration/hardware/wiring issues which I would have been able to easily identify if I was working with an engine management system that I was more familiar with. It's like learning a new language. You know what you need to say, just not how to say it.
I'm sure that a bone stock car would have been much easier to learn on instead of a 1000+ rwhp vehicle but I'm getting there.
I spoke to AEM yesterday regarding the ignition idle trims (same as over/under speed sparK correction in the stock computer) and fuel trims (reach/lean correction for over/under seed at idle) not working. We went thru all the settings and everything should be working but it isnt. I think all these issues are stemming from my TPS. I picked up a known good one from a friend today to try out. If that doesn't work, then I'll buy a new pigtail and run all new wires back to the AEM. Hopefully one or both those 2 things resolves my problem. Without these modifier tables, there is no way to fix the stalling when going from park/nuetral load to reverse as there is only one idle airflow table.
Because the map sensor is built into it and it's weather sealed, I figured it would be best to keep it as close to the gate (CO2 or boost signal in top port) as possible. Therefore we screwed it into the front of the pass side fenderwell under the hood.
