I have a 05 ccsb wit 5.3 z71. I have installed tbss port and polished it airaid intake wit kn filter pacesetter lt and true dual flowmasters. After i installed d longtubes and flowmasters i lost my bottom end wut can i do to gain it back. Still have stock tune

 

obviously a tune, and flowmasters suck. What size exhaust piping are you using?

 

You need a tune...

 

3in IN & 2.5 OUT I HAVE 4.10 STOCK GEARS ITS SLOW FROM 0 TO 70 DEN HAULS AZZ FROM THERE. WUT SIZE EXHAUST AND HOW MANY MUFFLER SHOULD I RUN. N E & ALL ADVICE IS APPRECIATED. IT PULLS OFF REAL LAZY THOUGHT ABOUT USIN MY OLD MUFFLER ITS A MAGNAFLOW SINGLE 2.5 in & and DUAL 2.25 OUT

 

The exhaust is fine... I doubt you will be able to tell a diff in mufflers, but some say they did gain from swapping to a diff make muffler.. You need to get with a tuner,check out sponsors to the right.. Just a tune will make a night and day diff..

 

Yea i plan on gettin a nelson tune. But do u think my torque will increase. I cant beat a escort rite now i apreciate yall advice. I need sum backpressure i believe becuz its flowin 2 ez

 

... damn.. my friend.. you have a major problem..

 

Its alright after im rollin a lil around round 60mph da lt and mufflers been on da since friday evenin. Its startin to run a lil betta each time i crank it up

 

I think you need to retune it.. 60 isn't worth a ****.. Get aretune before you go changing exhaust set ups... If the exhaust is flowing too much the FM'ers are stopping it.. Try out a retune...

 

I will get a retune n a few weeks. But still my exhaust sounds like crap real raspy i like a nice rumble without all dat poppin sounds. Plus 3in to much for dat small motor
