Right now iam currently running an 06 silverado ss lq9 with an ms3 cam from tsp. I mostly do in town driving and i was wondering if i were to switch to a tr224 cam if ya think my mileage with this cam would improve been running the ms3 cam for a while about 15,000 miles and i love the way it sounds but its starting to get to me mileage wise get about 10.5 in town and priemem is currently 3.50 a gallon and only going up. Just wondering what ya think any info. will help....ps the reason i say a tr224 cam because it is being givin to me my friend bought it new and never used it. Thanks.
