I was looking at some things online today while I was having my code issues as explained in another thread. I found that ZZP sells a Stage 1 throttle body for 199.99 w/core exchange. After I priced out all the sensors that I was looking at possibly replacing I noticed that the ZZP throttle body comes with all the sensors and is cheaper then replacing the sensors. Now my question is, has anyone purchased this from ZZP and if so, feed back pleaseeee!!!

It doesnt come with a maf does it?

im pretty sure that it does come with the maf. the listing i read said sensor included or what ever.Originally Posted by dsmuts

If the TB is bigger than stock, you'd need a tune because the readings will be off. And its un-needed because you cant outflow the stock one.
Its better to just fix your sensors and be on your way.
08-27-2012
okay. i was just looking over other options

Mustang and LSx owners see decent gains from being otherwise stock to upgrading their throttle bodies. I don't think bone stock cars are "outflowing" their stock TBs. To say it's unneeded is an opinion but you seem to be saying that it won't help him make more power... which it most definitely will.

Just checked ZZP, the MAF sensor isn't included. IAC and TPS are.

Without a tune it'll probably run worse
08-27-2012
Why would it run worse?
All a bigger TB is doing is allowing more air to be ingested per revolution. Same thing almost any bolt on does. Do these cars run worse if you add headers without a tune?

More air coming in is different than more air coming out. a ported tb messes with the ft's
08-27-2012
The MAF sensor stays stock.
Your statement is inherently flawed. If more air is leaving the motor that means that more air was coming in.
08-27-2012
I think what he meant is that more air coming in is different than air flowing out easier.
When I had my stock airbox, I removed my MAF screen and my idle wasn't too happy.
Also, what if you cut the MAF screen so that it only provides the laminar flow over the sensor? Leaving the rest of the TB unrestricted?
08-27-2012
When you add headers the inlet flow goes up. According to people in this thread that means your tune will be out of whack. It's the MAF sensor's job to see that extra air and add fuel accordingly, not get thrown through a loop with a simple change.
08-27-2012
The maf stays stock but it is seeing more air and messing with it. If you don't believe me go out and pull your screen out of your tb and check your ft's. They will be way off and cause KR
08-27-2012
Removing the screen can cause turbulence across the sensor... completely different. Porting a stock TB and keeping the stock MAF will do absolutely nothing to make the car run worse.
08-27-2012
The screen doesn't cause turbulence it smooths the air out.
08-27-2012
The tb from zzp doesn't have a screen in it and they recommend you don't use one.
08-27-2012
OP, getting a throttle body that retains the stock MAF will not affect your tune at all.
Good luck with your power/maintenance goals.
08-27-2012
incorrect. the maf sensor reads a small amount of air vs the diameter of the TB. if the sensor stays the same and that diameter increase or changes then the ratio is now different. the same amount of air will now cause a different reading and the ft's will be off and could cause drivability issues.
also it is true that removing the screen does not "cause" more turbulence, but it prevents the existing turbulence from being smoothed out. if you remove the screen then tune the car you can now account for the new variables as with installing this tb, it is recommended you get a tune.

Rob, This poster is incorrect in their assumptions. Like others mentioned, if you increase the size of the TB and keep the maf the same, then there is more air going into the engine (or available to the engine) which changes the maf reading and w/o a tune this is a bad thing that may run you lean and blow your motor.
If you need sensors, I'd suggest either finding a decent local JY or calling your local 3800 guru to see what parts he has laying around.
