I am looking to bring some performance back to my 05 CRD. I am considering the Eco tune. I have a concern though that I may have some sort of underllying mechanical problem that I should address first. I was hoping for some opinions about weather the tune by itself will help. Over time my jeep has seemed to loose its turbo punch. I just don't get that "push you into the seat" lauch anymore. My Jeep is higher mileage ~130,00. I also may have some TC issues as I have the no tourque to back out of my garage then jeep stalls when moved forwad problem. Will a tune likely restore the punch I miss or do I likely have other bigger problems?

Do you have a CEL on? The TC is a very common failure point. I would suggest running the CRD very hard every 2000 miles or so to get the exhaust temps very hot and burn off residual soot particles that tend to accumulate on the catalyst over time. This can be accomplished with wide open throttle accelerations from 45-75mph repeated 7 times. Pulling a heavy load up a grade will also achieve the same goal. This process keeps the exhaust restiction to a minimum and can help with turbo response issues.

The tune will restore the lost punch an also add some you never had to begin with! The TC can be fixed before or after the tune...but it will eventually need to be fixed.

Thank you very much. Oddly enough I towed a small camper this past weekend which may have cleared the exhaust residue ans you mentioned. My turbo response has been greatly improved this week. I will be saving my pennies (so to speak) for a tune. Thank you again.
