HV3 High Velocity Intake Insert

Yes it will (and sound awesome) however, I'd suggest doing just those 3 simple mods at the same time along with any maintanince that your car needs.

Is that better then buying a CAI? Sorry for the noob questions...the the three mods I should do is the PCM,hoome made intake and HV3 inserts right?
 


Tune should be last, first you put the mods on that you want then you get a tune telling the tuner what mods you have so he can adjust the tune accordingly, if its a mail tune you order.
if you have a tuner in your area then the tune will be that much better cause they can tune to your exact car.

I made my intake, got the downpipe, got the hv3, then got a custom incar tune from :: Overkill Motorsports ::
as for beating a stock gtp.. I beat a stock bonneville SSEI which is the exact same car as a gtp, but the bonneville is 300 pounds heavier and longer geared so im guessing the gtp would be just as fast if not faster as my bolton car. driver race really.

but at the same time i pulled a 15.6 in the qtr mile.. stock gtp's if driven right are 14.5-14.9 in the qtr
 
I've never done a case learn with swapping pcms. You should be able to pull the old pcm out and put the new one in and fire it up and go. No need to spend $200 bucks. Use that money and buy headers.

my friend told me I be fine with just a CAI and new headers, no PCM, is that true?
 
If you want a little more power then go with the following mods on a GT

Intake of your choice
HV3
ER Rockers or cam
Plog/Down pipe or headers
Exhaust
Tuned PCM

I'd recommend performing the routine/preventative maintenance as described in the "safely modding your 3800" thread before spending any money on modifications. If you can't perform the basics you're going to be at the hands of dealers and shops who are "modding" your family sedan. If you can work through the maintenance items, you'll likely be much more comfortable around your engine and likely able to easily perform your own modifications. You'll also have a variety of tools and a car that is in great mechanical condition.
