So the saga continues - a month ago I sent back the ZZP PCM I had just purchased because the shift points from 1st to 2nd was 5500 rpm where it was supposed to be programmed at 6k. Plus, the car was performing worse with the new zzp PCM and 1.95 rocker install than before. When zzp shipped back my reprogrammed pcm a 2nd time, it seemed the car was running better and the shift points did go up to about 5,850. Last night was the first chance I got to test at the track. Earlier in the day, the car was still shifting around 5,800 or so. I thought for sure I'd get some decent runs in. Turns out, on every run and even driving afterwards, the car is now shifting at 5,500 again no matter what I do? Now I'm thinking
To make matters worse, the car seems to get off the line ok, but then in the top of first gear and in second gear, it just seems to dawdle along. I'm certain the pcm is the culprit unless anyone knows of what may cause the sudden change in shift points?
I can e-mail zzp, but even if they agree to reprogram, I don't want the down time again on my car and have already given them two chances to get this right. Plus even after I installed the 1.95 rockers and the pcm, the car ran slower than it did before the two changes by a couple tenths. When I dropped pulley sizes by a tenth, it got me back to where I was before all the changes. Does anyone know a reputable programmer within 100 miles of Chicago that can program the pcm correctly and stand by their work?
