Hi i just bought an ls4 throttle body.from a member here ,great site by the way ,and i was wondering if i can drive my 07 ss sc with stock tune with that tb ,untill i got myself a ottp stage 2 package ,the reason im asking this Is because i dont want to drop the stage for now and my tb is pretty weak (keep accelerating at slight throttle)

 

no

 

^ yup. The LS4 TB has a larger diameter than the stock tune is designed for. You will experience all kinds of stutter and choppyness if you try to run it without adjusting for it in the tune.

 

plain and simple...

 

Hehe thank you very much ill wait

by the way if i have i/h/e what the best stage to get for performance
Ottp stage 2 zzp stage 3 or gm stage 2 ???

 

I'd go with ZZP Stage 3. GM Stage 2 was designed with warranty in mind so it will be more reliable, but it is not the best for performance.

 

Great ,i did notice that on the web site on ottp they remove torque management let you choose the rev limiter and also tune for the ls4 ,i know its only option but are zzp able to fine tune like ottp ?

 

Nope, OTTP Tuning is WAY better than ZZP. If you get ZZP tune then something wrong with it they won't get back to you ASAP! And ZZP is canned tune. OTTP will get back to u ASAP! Josh from OTTP, he has text and you can text him. OTTP is worth of your time. I have OTTP tune in my car and it's worth it.

 

Josh know what to do with LS4 tuning.

 

OTTP is great from a workmanship/tuning standpoint, but they usually have too much on their plate to give proper customer support. I've spent thousands of dollars with them and know all too well.

 

Thanks for the input ,ill get the ottp stage 2 then

 

I can get daily updates from ZZP so not sure what some of these people are talking about.

I would stick with ZZP over OTTP. Both companies are great but i have spent 5k more with zzp than i did with OTTP.

 

I've never had a problem with zzp and have about 6k with them...I just got a custom tune instead of their canned tune

 

nobody cares how much of your money you spent with who

 

And I'm nit saying they should just stating a fact that they have backed me up with every purchase

 

I got my tb ,is there any way to mount it without the adapter plate ??

 

You can either get your supercharger ported or get throttle body adapter from ZZP. They got good price for it. There is good and bad from ZZP as well for OTTP.

 

Yup get a TVs fits like a glove :-)

 

lol yep its true the TVS was designed with the LS4 TB in mind
