I want to see if we can get enough of an average stock power band to compare too. I will post mine to begin.

P.S. This is my mom's stock 1991 Q45 compared to my 1990 with the switchable ECU set to level 3. Her's is the one with most power.

I want to see if any other stock Qs will come close to her's. This will help me determine if her Q is stock for sure.

Thanks

Matt

Yeah I know. I have done just about everything I know so far except to check for plugged cats. I used the Consult II on it a couple of days ago and watched the o2 sensors on both banks to see if one side was running richer then the other because I figured that maybe when the previous shop did the guides that they may have got one side off time a notch but both o2 sensors are giving equal readings at all times so seems good there too. Only other thing I can think of is the cats. go to my profile and see what I posted on what I have done so far if you want so you can get an idea of where I stand now. I would like to get one of those home made consults that all I need is the cable and software so that I can perform the same as above when I'm not at work. I just don't want to end up ordering the wrong stuff.

Jeff Williams,I noticed that you have different power readings at 3 different times. Do you also have a switchable ECU? I noted that you get less power in the second run then in the 1st. I also had pulled 3 runs and in the same order the second run was less then the 1st and that was with it in level 2 mode. Level 3 brought it up about 5 HP from the first run while level 2 brought it down by about 5HP from the stock run.
