what needs to come first?
Now that have finally bought my first Vette the question came to me. Where do I start?
I have a 2001 C5 automatic all stock. Should I start with a performance chip or a larger throttle body or headers and exhaust? I do not have this problem with my 68’ 440 Roadrunner. First off there is no performance chip. What set up worked the best for you?
I wanted to also see if you could opinion of the different manufactures of performance chips. Are there big differences and which one performed the best for you.
I’m not looking to drag race the car, that’s what the roadrunner is for, but I do want quicker throttle response, I do plan on autocrossing.
Any help would be greatly appreciated. I’m very proud of my car and can not wait to show it off at the first car show I can find,
Thank you in advance,
Sui





Personally I wouldn't waste money on a chip or programmer....get a new intake...Blackwing or whatever...headers and exhaust then get the car tuned either LS-1 edit or HP Tuner.....those mods will run ya ~$1600 plus probably ~$300-350 dyno tune....and if you shop forum vendors you can probably get the stuff for a little less





You were in the same boat I was when I got my Vette. I had owned a multitude of older hot ros - everything from FLat Head Fords to my last GTO. The Vette is a whole different (and far better) world!
I started off with replacing the CAT back and the airbox. I went with the Blackwing air cleaner and have been VERY happy with it. It gave it a lot more throttle response, and improved the motor sound. The CAT back gave NO hp (the stock exhaust apparently is pretty good) but changed the whole attitude of the car with the sound.
After this when the $$ was ready - I got a set of Long tube Headers and Hi Flow CATS - I understand LT's are not legal in CA so that may not work for you.
You could jump right into a new gear set for your rear - this is a GREAT mod that gives INSTANT feel and acceleration results. After that the sky is the limit I have found!
Main thing is to have fun!
See if this makes sense:
Without going into the bottom end of the engine there are five seperate but related areas you can mod for incresed performance.
First, you've got to get more air into the engine.The best bang for the buck is a new air intake ( do a search to get 3 million opinions on what we think is best). But that only starts the air into your engine - now you've got to decide if you want to stay NA or put in a blower. A blower will get the air in , no prolem. But if you go NA you want to do everything you can to "open up " an airway into the engine - so, think about a new MAF, TB and intake manafold- that will provide a wide opening to allow air flow in.
The "new" tech isn't all that new, it's still true that the more air you put in the more air you have to get out. Once you open up the air intake you have to consider getting the air out of the engine.
So second, you've got to think about headers, hi-flo cats and cat backs as a PACKAGE. You don't have to buy everything all at once but you should plan what componets you'll put in based on what your research tells you is the best setup for your goals.If you're going to do the install yourself it dosen't matter what parts you put in when, but if you're having the install done, from a labor cost aspect, you'd like to do it all at once.
Third, no sense letting more air in and out if your engine can't take full advantage of all that air flow - you need to think about heads and a cam, again as a package, with all the peripherals - ported oil pump, dual timming chain etc.
Fourth. lets get all that power to the ground - you've got to loose your stock TC and get a new set of gears with a high stall Tc and trani cooler.
Fifth, find a real good tuner and turn him loose on your car.
Now what order you do 1 thru 5 is up to you - some will suggest #4 should be first and # 2 last - it's up to YOU to decide what makes sense to you and your pocket book.Again , from a labor point of view, each "chain" should, if possible, be done at the same time.
Good luck with your mods and don't be afraid to ask questions -there's alot of nice and very smart people on this forum that will give you a lot of help.
1. Replace the restrictive air intake (everything forward of air bridge)
2. Ported throttle body (Shaner or Lingenfelter)
3. Upgraded anti-sway bars (Z06 or Hotchkis)
4. Wider tires/wheels
5. Tune (including adjusting shift points & firmness)
Everything else that has been mentioned would be "icing on the cake," but not strictly necessary for improving throttle response or auto-X performance. You can also go crazy with handling mods - lowering (free), shocks, springs, tunnel plate, or even a full coil-over system.
Enjoy!




1. Gears
2. Intake
3. Exhaust
4. Heads/Cam
5. Blower
I have a 2000 A4 and I went with intake (blackwing), exhaust (magnaflow), and headers (dynatech). And a dyno tune. However, although I enjoy the sound of the new headers, they did not give me the power I was expecting. Unless you plan on cracking into the engine and doing a heads/cam package or a blower I would forego the headers. If better response is what you are looking for get yourself a higher stall torque converter (3400 or 3600) and some new gears. You have an auto so you either have the standard 2.73 option or performance 3.15 option. Go with some 3.42 or 3.73 gears combined with the torque converter and you will be very happy. If I was to do it all over again I would have purchased the gears and TC first rather than the headers. good luckby the way, you dont need a performance chip. But you may want to get a dyno tune after all of your mods are finished to optimize everything. it will defintely be necessary if you change gears.

An excellent post. BTW, click the Mods in my SIG for a complete list of mods done on my 2001 C5 Coupe, A4 [3.42]
Now, go out and drive that car!!
Have fun!
