my car is currently a bone stock 99 GTP and i was looking to make it better just kind of a side project nothing to fancy, i was thinking of putting headers and an open cone on soon but do you guys think this would be enough flow to run a 3.6'' pulley?
 


well i dont want to get a tune, i have a scanner for KR should swap to a 3.6 and see if theres any KR if theres not then im good to go?
 
With every modification you do, no matter how small, you will definitely want to re-tune your car to take advantage of the gains. A tune is the one place you don't want to skimp. The wrong tune is what makes a heavily modded car slower than a car with half the mods.
 
your telling me new headers require a tune? cone filter requires a tune? stuff like that, sure i can see how a tune would be nice but i dont have the money for that plus i dont know of any places around here that do that
 


ZZP is all the way on the other side of the state if someone was close I wouldn't mimd gettimg a tune from them but is it really gomna hurt the car to not have a tune?
 
Its not going to help. If you're gonna spend the money and time on headers, dont you want to get the best out of them? Just to use an analogy, I can buy the baddest TV out there and upgrade to the fastest cables they have. But if I leave it on the default settings, it's still gonna look like shít.
 


I ran untuned on my rocker 3.4 setup for a little while. Even throwing the zzp 1.0 pcm in instead of a real tune helped it out a lot.
 
Honestly...an easy bolt ons project would be as simple as...

Headers of whatever kind you want...they all do the same crap....

Get a dremel...hog out the blower outlet for lower outlet temps...

Get a ZZP MPS, and hell...have them toss it on the dyno and then throw the 3.4" on and a re-tune just to see the gains...that'd be worth it IMO...that way you don't have to waste your time with a canned PCM from ANY vendor.

Toss some new plugs/wires on it...along with a 180* T-Stat so they can lower the fan turn on points and flip the square dog bone mounts for better power transfer.

And for sure, just toss the cone on there...that'll help out too.
 
I wanted headers and the open cone just for better flow I thought id be cool to drop the pulley size but not if I have to get a retune
 


i have a way to scan for KR. dropping the pulley size isnt my primary goal. just trying to get a few extra ponies with some more flow
