I don't like the shift points on my 09 f150 5.4.when towing. Will a tow tune from 5 star improve the shift points for towing? I didn't know the pickup had 3.55 axle gears when I bought it. Need to have better shifting and a boost in power.

 

I have 5 Star Tuning on my 5.0 and substantial improvements with my 87 octane tunes. You should see similar results with the 5.4. Their Performance/Tow tune is great for a daily driver and works well with that gearing. I have the 3.55's, as well.

 

Does anybody know of any discount codes for this tuner

 

I got my SCT tuner/5 Star tunes from Stage 3 Motorsports. They have a coupon codes for spending certain dollar amounts, also.
