Got my truck dynoed today it put down 255 rwhp and 300 foot pounds of torque. I also found out that my truck will go up to 145 mph. It is a 5.3 rcsb superchips tune (crappy) Borla exhaust, ASP pulelys, KN FPIK, and Free Mods. My next mod will be a Nelson Tune, then Thorley longtubes or a 212/218 cam? Which should I do next?

 

Sts!!

 

 

 

Well you will have to do the nelson tune to see the results and idol quality out of the cam. So if you don't have the money do the headers or the nelson tune and then get the cam and redo the tune. Good numbers

 

shift kit and converter.

 

Just my personal opinion I would get a Nelson tune next! The reason why is because he can make the most out any mod you do and any time you want to get a updated tune it is free except for shipping! Get a Nelson tune and also get a Transgo shift kit so Allen can remove all your TM safely!

 

about how much does a nelson tune cost for a 5.3l?

 

99-00's are $375
01-02's are $425
03-04's are $490

Everyone of those prices is well worth it especially with free updates for life!
