The cost was $750. The time the Jeep was down was 6 days for the mail out/return of the computers. Removal was pretty easy. for the TCM, I removed the air box first, then the vac assembly was swung to the side after you pull the 2 base screws. The ECM was best removed once the battery was out. This gives you the room to push the huge wire harness cord out of the way for a no cursing bottom nut on the braket removal. Realy a peice of cake job to get both out in this way.
The jeep started up normaly and did in fact have slightly less clatter. The ORM cel light went out in a few seconds as the MAF was now pluged it.
A slight power increase is noticable at WOT with the ECO tuned ECM. But the real change is how this trany works! I can now hold OD lock up down to 51-52mph and accelerate moderately with out loosing my OD LU !! This is exactly what I was after. Even 4th holds lock up without the free wheeling TC on either side of 4th down to 1500 rpms easy.
I must add, I luged this thing at the edge of gear change numerous times, searching for the slightest hint of vibration torqing of the drive train..... nothing. The gear releases were clean, lock ups smooth, gear hunting was not found (no trailer). I cant find a single issue with this TCM tune. Zip...nada.
Id like to thank Keith at GDE for having the tech know how in fixing these all important drivability issues. GDE makes this CRD worth owning.
Now, the new dream is CRD #2 with the 4X4 converted to 2 wd! If that gets close to ALH/TDI MPG territory.... That would put a V-dub up for sale
I have the Full torque Eco tune and pre F37 TCM with shift points very close to yours. I think it was non winterized fuel and I was close to the refinery in Mississippi AND figuring in the 5% odometer error 
Three Adults with luggage and average true speed of 70 MPH per my gps, not the indicated 75 on the speedometer.
Iv been on Freds for 9 years since my first TDI and your readings of 70 mpg under those circumstances is seldom posted. My beetle 5 spd's best hiway ever was 47 mpg. The other 2 TDI's run 36-43mpg which just happends to be in line with what is normaly encountered. But hey, why dont you post your findings in here and blow the milage doors off all these other 99 jettas cause there talking low to mid 50's for best hi way.
la-la land. The "why? because I can" is going to bite us all hard, VERY hard some day. its not far off. JMO 
I've been a member of Fred's tdi club since I bought my 1996 Passat in 96 
Way back I owned a 1982 Datsun bought new, before they were called Nissan, King cab Diesel pickup that my average was in the low 30's. I only kept that one for about 20k miles because the rpm band was too small and I was constantly shifting 
My first diesel was a 1978 rabbit 4 door also bought new and my high tank for that one was 64 and the tanks on both side of that one were also high indicating it was not a overfill/underfull thing and again at about 20k miles after it was broken in. I was alone with one suitecase driving the speed limit per the speedometer.
