Diesel911,

When making IP timing changes, keep the following in mind; Unless your IP is brand new or recently re-calibrated, one cannot be assured that every IP will react the same to these changes. Additionally, the mechanical condition of your engine will affect overall performance too.

Keep in mind, as stated in my original thread, the important thing to keep in mind when advancing the camshaft timing is to advance injektor pump timing the same amount in camshaft degrees.

Your decision to pull back your IP timing based on how the engine reacted to the change was prudent.

No matter what you read, always, always, always believe your actual results...Robert
