Just finished a cam swap on my 09 chevy 4.8. I already have Long Tubes, full exhaust and a cold air intake. I was wondering if it would be better getting it dyno tuned, or if a mail order tune would suffice? Does anyone have any recommendations on a good tuner to get a mail order from? Or any good dyno tuners in or near Maryland? Thanks for any help?

 

Live tune with HP Tuners or EFI Live. Dyno or street tune. Don't do mail order.

 

You will need a few adjustments made from your base tune so I would say dyno or street tune. No sense in investing with a cam then not finishing the build without a good tune.

 

I see you went long tube instead of short. May I ask why? I have ano 03 4.8 and have read that because of the low end torque short headers would be better.

 

What part of MD??? I went with tuned by frost because he could do both and was close enough i couod drive the truck to him to get a full street and dyno tune done, cost a little extra but i dont trust the tuners in town...... 2 hour drive was more than worth it as far as i am concerned!!!!
