Have a 2008 auto with ripp sc. Running 35s with 3.73 gears. I know I need to re-gear but im waiting to buy new front axle. Can someone tell me what my shift points should be set at. It seems like I have no third gear. As soon as it shifts to third it jumps right to fourth. Any help would be appreciated

 

How are you going to reprogram it AEV or other? You need to change the tire size and it should fix it.

 

Pretty sure his supercharger came with a programmer like bullydog so I think he is looking for specific tune settings. I doubt this is as simple as not changing tire size.

 

The tune you got from RIPP should have adjusted them for you. Did you give them your correct tire size and axle ratio? They asked for mine and it was included in the tune. If you didn't you should contact them and have them adjust your tune.


On a side note, 35's and 3.73's with an auto are pretty steep. Are you sure it is not just the torque converter locking up in third? Don't have the chart in front of me but with your tires and gears you probably are only turning 1700-1800 rpm in OD at 70.
