Happy FICM Tuner Owner
 

Purchased the FICM tuner and received it the last week of June. I did a ECM rollback first and then loaded the FICM tunes.

Started out running the Atlas 40 and stock strategy for a week. Did notice an increase in low end throttle response and power. Then I reprogrammed with the Atlas 80 and ran it. More of a noticeable increase in low end throttle response and power.

The week of the 4th July, towed 5R to river using Atlas 40 and Extremely Heavy Tow. Was very satisfied with the way truck pulled thru entire rpm range.

Running custom tunes on Gryphon CTS. Only problem still have hard shifts on the 3 tunes I have tried and need to get Bill to adjust them. Switched to using SCT and custom tunes and still impressed with the combination of the FICM tuning and custom tunes I have for SCT.

In my opinion the FICM tunes would be my first choice to improve performance and then add custom tunes next. I haven't tried the Economy or the Hercules tunes. Probably won't run Hercules as not recommended for non-studded trucks the way I understand.

Thanks PHP
