I'm going TVS since I have all the cooling mods already for it and because i want to keep my torque numbers higher also. Any meth injection will work fine, meth is meth.

 

Yeah removing it on a stock engine is not a very big deal, but if you're planning on pushing up to 350WHP with OTTP stg.3 then you have a serious amount of power. Without TM you could have some problem (which I don't want)

 

When I go to install my h/e and option b tank, should I just buy a dual pass and do all that at one time while I have it all apart?

Also how hard is it to install a dual pass?

 

Well you need to take off the S/C to install a dual pass and if you are going to all the work to get 350WHP and doing an OTTP stg.3 kit and don't instal dual pass... well your dumb! So YES you should have one and any monkey with a wrench can install one!

 

I would do everything at once. like the h/e, dual pass, and opt b

 

That is the way that it is done!

 

So starting with a h/e, opt b, and dual pass, I should have enough cooling at that point for the tvs?

 

From what I have heard yes! This is what I am planning on doing primarily and then adding meth! With a H/E, dual pass and option B you should be safe with either a stock pulley or 3" pulley for sure!

 

I think this is what I am gonna do, ottp stage 3 with ottp h/e, opt b tank, and dual pass, and get it tuned fairly safe, then after a little while install a meth kit and tune it more.

At this point my questions are a little off thread topic but how to the meth kits work? Do they constantly spray when the car is running or only when you hit the gas pedal?

 

it come on at a set psi

 

hahn is more expensive with lesser powerband and more extensive install. ottp stage 3 is an easier install with i higher powerband and is also cheaper. honestly though, i have to say that as a fan of both, you'll most likely be more likely to reach more with the hahn and be more satisfied with their services. not a bash to ottp, i like them a lot.

 

i need statge 2 mounts, ottp rotated mounts and i guess hahn catback to be set on ur list

 

How do you hook it up, wire it into the ecu?

 

you either use a boost line or tap the map sensor

 

Oh ok I see

 

Hmmm. I believe most everyone with extensive mods has torque management removed... Can you cite any sources that say TM is good or bad with power? Rotated mounts, upgraded suspension, axles, etc, should save you unless you totally break your tranny. I would believe that TM would be shooing yourself in the foot though with any setup really, as it would cut power when you needed it during a race or whatever.

 

BlackSSNick... If you are planning on this set-up I would suggest 3" intake, LS4 Throttle body, and stg.2 rotated mounts

 

Is ottps cai 3"? Because you can get a bung for meth nozzle which will be perfect

 

You betcha buddy! You will have to go to an auto wreckers to find an LS4 TB:
Here is the list of vehicles you can get one from:
3.5L colorado 04-05
3.5L envoy 05
4.2L trailblazer 03-05
4.2L hummer h3 06
4.2L bravada 03-04
4.2L envoy xl 03-05
4.2L envoy 03-04
4.2L impala 06
5.3L isuzu ascender 03-05
05-06 trailblazer ext
4.2L canyon 04-05
3.5L monte carlo 06
5.3L trailblazer 06
4.2L rainier 04-05
4.2L sab 9-7x 05-06
5.3L envoy xuv 03-05

 

ZZP sells the LS4 TB's too for $99.99

 

Yupp most people with a lot of mods remove it... There are dangers for sure! I looked for the thread, but couldn't find it. If I do, I will send it to you! I also chatted with some of the local tuners and they said it is personal choice! Removing it will give you more hp, toque, better and faster shifts, but it comes with a danger

Didn't know that! Good to know... (Do you have link?) I know a guy that works at the local shop so he just pulled on for me and I got it for free

 

Do i really need an ls4 throttle body? It just gives improved throttle response forrect...is that the only benefit?

 

blah ls4 tb and stock one. ahh i can see the argument starting all over again

 

It is bigger than what you are running stock and give you better response and if your going with a 3" intake I would suggest the bigger TB...

 

Alright, makes sense
