Performance Question

[street_fire]

Ok I have thinking to get a ported and polished upper and lower intake along with a 65mm Throttle Body. All by Milzy Motorsport. So my question is that do I need to tune my PCM for theses mods???

[young gun]

You don't need too. To get the full potential of them you do.

P.S. i would recommend CAI and a Catback before doing this. Also headers would be a sweet addition but not needed. Also the 65mm throttlebody is not so necessary either unless your going boost. For N/A purposes a 62mm would be fine or even stock until you get headers and ported heads.

Glad to see another person from windsor on here. I agree with youngun, You should get a cai intake installed and a non restrictive 2.5" catback first. Then when you get a port and polished upper you'll start to notice some real gains. Most mods support themselves, have fun!

[HOYS]

Why would you not tune the PCM? I think its an easy mod that everybody should have.

A cat-back exhaust is not necessary before a 65mm TB. Also, a 65mm is applicable for any application, not just boost.

If you don't want the tune, don't get it. I still recommend the intakes and TB no matter what.

Everyone forgets about the DP when doing the exhaust. The DP is one of the most restricted parts on the GA's and no one seems to replace it. What I would do If I was you would be to get a CAI first, buy the custom 2.5" DP from Milzy or have one made, and then replace the CAT back system. After you have done that then replace the headers, and then after that replace the intakes plus TB. In that order you will get the best bang for your buck.

the aftermarket headers available are sorta blended into a downpipe. so you get a 2.5 dp when you get headers.

Milzy sells the down pipe seperate, gives ya a deal on it if you purchase his headers.

The headers go down further than the stock setup, so you need a custom DP for headers compared to stock.

yeah, pretty much disagree with all of this.

First off, replacing the TB with a bigger TB won't do anything if that isn't the most restrictive part of the intake. It won't do anything if all that extra air has no where to go because there are other restrictions. Same reason people don't need to replace their MAF with an LS1 unit when they aren't even breaking 9000Hz on the signal yet.

A tuned PCM is great, but you won't get much HP from it without other mods, and you get more from the PCM if it's tuned for the mods you have. So if you have an idea of what mods you'd like, get them first then have the PCM tuned.

The DP is not that restrictive either. It actually has much better flow than the rest of the exhaust. The restrictive part is the stock catalytic converter. The most restrictive part though is the stock exhaust manifolds. Headers give a huge gain. If you plan on getting headers, don't get a downpipe because you'll have to replace the whole thing anyway when you get headers.

I'd get a CAI and a cat-back exhaust first, and a high flow cat at the same time if you can. Then headers. Yes, you can get a larger TB any time after that, but don't expect huge gains from it. The more flow you have from other mods (ported mani's and heads, cam, etc) the bigger the difference the TB will make.

[G.I.Ceo]

I used Milzys DP for a long time and when I got a set of S&S headers I had the DP chopped to have it fit the headers. Didn't cost much at all to do.

Thanks for the stab about the LS1 MAF sensor Aaron. I know now I didn't need it and the reason for it. I guess I should have never asked but how would I have ever known if I didn't ask? I have a learned a lot from your info on here and I thank you for that.

[street_fire]

I got a CAI in my right now. I got a magaflow cat, pacesettler exhaust and a tuned PCM coming for MPracing in the mail. I also got a engine mount and trans mount ordered from Milzy Motorsport. So hopefully in a month my car would be golden

Cool.

Sounds like OP is in good shape to get ported intakes and a bigger TB.

just curious, why milzy. wot tech parts are flow benched and ported based on best flow, not most volume

Flowbench designed. They don't flow every manifold from what I'm reading.

Milzy flowbench designed the intakes as well. There isn't much you can do to an intake when you port it. There aren't many "tricks" as WOT-Tech says.

I was thinking Mizly beacause i was on their website ealry today and WOT-TECH had slipped my mind.

So I don't need to tune my PCM if i get ported upper and lower intake and a TB. Just remember i just thinking about about it. But i might just get headers before port intakes.

I think you called Milzy today, correct?

You don't need a tune for ported intakes and a TB, but a tune would be a good compliment to your mods. Would really wake up your car.

No I didn't call Milzy. Well that's good that don't need to tune the PCM for port intakes and the TB. I got a tuned PCM ordered from MPracing and hopefully it cones in soon.

[MAC the KNIFE]

currently, my car has p/p intakes from WOT tech, and a 65mm tb, and cai. the intakes noticeably increased the car's power around 4k rpm and higher. the 65mm tb and the cai didn't really make a difference that i could feel. and that's all on a stock tune.

for you, i recommend headers and intakes first.

[street_fire]

Does it really matter where I get the ported intakes from Mizly or WOT-TECT??? They both have good intakes and they are good companys.

people will fight for days over this....

But i believe this....

just go with what is your price range, shipping (ones in Ohio the other i believed just moved to Florida)
