what year CSVT?? then we can really help

oh yeah and gut the pre-cats, its a good mod, also the y-pipe optimization is really good

people have problems with the MAF's because they kinda bypass the PCM they tell it more air is coming in then there actually is and so it can cause your engine to run rich, its not a good thing to start with(i think that is how it works)

best first mods would be

mod 1

THIS HELPS OUT A LOT, TRUST ME

mod 2

this helps a lot too, but not as much as the first

this next one is a must even if you have exhaust you need to do this

mod 3

you will also need some mil's when you do this so here is a link to make those


MIL's

next comes the really easy stuff

get a MAF adapter and a k&n ru-3530 cone filter, next get/make some sort of heatshield

after that comes some more expensive stuff like a LSD, flywheel, clutch, Returnless LIM, Port matching Manifolds, MSDS headers

only cause im feeling nice today, next time like the others said search

98.5 Black SE ATX S&B filter, SVT MAF, optimized SVT TB, mesh grille, removed orange reflectors, painted rear reflector, gutted pre-cats, optimized SVT LIM, 19lb injectors, resonator removed cant afford an svt but lookin for 1 in nc
