The data log indicates MAF & TPS voltage & RPM increases also so thats normal.
but it is a large jump agreed, something isn't quite smooth somewhere.

possibilities;
1. MAF is faulty
2. MAF experiencing turbulent air flow
3. knock and main maps aren't same and ecu is switching to save engine.
4. TP scales not smooth
5. fuel map commands too much enrichment
6. Incorrect MAF VQ
7. TTP scales
8. Accelerator enrichment is too steep.
