Ok I know that long tubes give me more power than shorties but how much of a difference can be seen from switching from shorties to long tubes. In 1/4 times and SOP effect?

 

I noticed a huge difference after I switched from my Edelbrock shorty headers to my Pacesetter long tube headers. way more low end and top end power. I highly recommend. Even makes it sound better too.
good luck...

 

good that what i wanted to hear, sold my shorties last week and ordered the pacesetter lt's. Havent recieved them yet hopefully to day is the day or manana. How many tenths u think it will drop me, do I need to retune after install?

 

you need to tune out the rear 02 sensors so you dont throw any codes. the codes wont hurt your truck though

 

yeah thats taken care of, i have no cats, and allen has already removed the rear o2 sensors

 

you don't have to retune with the lt's , but it would be a good idea(More power, runs better/smoother)......
