Welcome...

I would start out with a cat back, air lid, and a fast toys "ram air". All 3 can be done for around 1,000 depending on the parts you chose.

thank you i will look in to these.also I was told that the g force chip was a waste of money but it was on the car when I got it. so do I leave it or get rid of it

Im not sure how that Gforce chip is wired into the car, so it may be simple or a pain if it was cut and spliced.

Honestly most bang for the buck would be plugs, wires, lid, filter, used catback (they pop up in forsale section all the time) and a tune. Should easily net 30-40hp and a nice seat of the pants kick. What transmission is in the car?

SPAZ-3

also look into maybe buying some 3 way adjustable shocks, lowering springs and a sticky tire . youll be amazed how it runs

Stephen Medley

the chip is wired in to my intake it looks like it might of been done proper but I am a newbie soooo cant say for sure I can take a picture and post it if that will help. but its the a4 tranny and im going to put some new tires on her today, also the car has 140k miles is it smart to build this engine or save for a new swap

Stephen Medley

I hope its done right

headers, ls2 intake manifold and throttle body, tune then once you get the money catback air lid.

Tune up, lid, exhaust, tune, stall if you can swing it. LS6 intake outperforms the LS2.

Ditch the garbage chip, not knocking on your car at all, and get a lid, catback and a dyno tune.

N20zuki

Why are you recommending a intake manifold that a stock LS6 and throttle body out flow?

Sleek, sexy car, looks awesome white, but I have to say those wheels are hideous man. Ditch them, even stock rims wud look better. Awsome car tho. And agree with above, lid, cat back exhaust, ls6 intake etc.

Stephen Medley

yea not a big fan of the rims. I got the car as is. got the chip off and it ran like **** soo now what, not to happy with this. so I took it to a garage and they said the chip was tuned for this car not a smart move to get rid of it so I got to pay to have it put back on and it runs sooo much better. 35 more hp 42 more tq and 3 mpg more. wtf

What type of garage did you take it to? If the previous owner had the car tuned after installing that chip and the MAF tables are all adjusted, I would do your first round of mods and take it to a local reputable tuner and have the car retuned with the chip gone and your MAF wires spliced back together.

Stephen Medley

I live in Fayetteville Arkansas so I took it to a place called a@e dyno in springdale Arkansas, other than him I would have to go out of state. and he said just what u said conan the chip was put on the car and then he used a diablo tuner to tune it to the ECU?? im not sure if he was trying to work me over or not like I said im very new to this and I don't want to mess up my car all he said was and I quote "this chip has been tuned and modded specifically for this car DO NOT take it off again u can do any mods u want with it on" end quote. what do I do, where do I go, I need someone who I guess is a specialist with this kind of thing. that why I came to ls1 tech.com

If the guy you took it to knows what he's doing on the lsx platform he should have told you he can remove the chip and reflash your pcm to stock. I would try to find someone with HP tuners and have them flash a stock tune back in your car. Or you could always send the PCM out to a sponsor and have them do it.

Stephen Medley

ok that's what im going to do. i'll just send it out.
thank you very much

DaytonaBlues

before you send it out, wait wait until you get a lid, catback, do the free mods (like A.I.R. and EGR delete, and if you dont have to deal with emission tune out the rear 02 sensors so you can run an off road y pipe. I think for around a grand, probably a little bit over though if you go with affordable pacesetter long tubes and an off road y pipe, not to mention the cat back (or just throw on a cutout before the stock muffler), lid, and the PCM reflash. If you can afford it you gotta send that PCM out anyways just curious if whoever is gonna do the pcm work can put a tune in there so you at least can ditch the AIR and EGR system. id say easy 400 horse with these. Tune though is the secret and making sure who does it knows how to do it correctly. just my two cents

garygnu

Frost on this forum dose great mail order tuning .how exactly dose that chip work ?

Stephen Medley

all the work I will be doing will be in a few months, im trying to save up about 2,000 or wait till income tax time, we get a nice chunk with 4 kids, all im wanting is around 450 or so horses. not to many people around here are even keeping up any way. the car seems faster than it should be or is it just me.the new 5.0 mustangs and even the new Camaros both 5 speeds just cant hang idk maybe the drivers just suck
