over time my car has gotten to where it has no low end at all and the exhaust note is not nearly as loud. what could i do to gain lost hp? it seems to still run just fine except it makes a weird scratching noise when its cold.

 

Can you give us some details on your car (miles since last tune up, total miles, current mods if any, etc)?

 

64k everything has been done within one year except plugs/wires.

 

it's been awhile since i posted hear....probably a year or two, however, did this problem just arise or has it always had a bad low end? 3.8's dont have the best lowend torque however you get them above 3000 and they move.

 

have you noticed a drop? or just its not good?


Also how many miles on your CAT... my CAt went out at 37k... hurt my performance

 

it has dropped. i even have more wheelhop. original cat.
