I just tweaked the ALDA in my car, with a noticeable increase in off-the-line performance. BUT, I have also noticed that it runs at higher RPM's at highway speeds than it did before (3400 vs. 3200 at 70mph), AND, it seems to have less pick-up once at highway speeds. I reversed the adjustment by 50%, and I've found that the highway RPM's are lower, and highway acceleration has improved.

So, by adjusting the ALDA, am I just trading highway performance for better low speed performance?

Has anyone else noticed/experienced this? Any ideas? Maybe the turbo boost is inadequate?
