I just got my new motor for my truck started up today and drove it around a little bit. Its a 04 ls1 with stock 241 heads and a MS3. Just wandering how driveable this camshaft is with a good tune. Im driving around on a tune for a smaller cam and 5.3. It starts and idles decent at around 800. Anything under 2k rpm when driving and in gear it bucks really bad. But over 2k rpms it drives pretty good and the sound at a idle and driving is insane. Also if anyone can chime in on if it is bad to drive around with a tune for a 5.3 on the 5.7.

 

The bucking can be tuned out if the tuner knows what they are doing. I daily drove the **** out of my CETA and it had the MS3/PRC 5.3 heads on it.

Again it's all in the tune

 

All ur issues can be cured by a good tune. I daily drove my 98 z with a ms3 for 2 yrs with a TSP tune and never had a prob!
