i get 15 at idle...20 when decelerating in gear...

 

those were supposed to be negative numbers, by the way.

 

yeah, vac, not boost

 

just got done installing my second zpi kit tonight, long story sold the first one because it wasn't running right, then last week bought a custom stage 0.5 for a smokin deal. I now understand why everyone loves these kits, hearing the hks blowoff, I just can't explain it... I love this kit!!!!!

 

mine was great for the first 4 months. then it was a POS

 

Just for referance, how many pounds can be ran on a stage 0.5 with out any managment??? I installing a boost controller and am putting in the 3 pound spring, so just need a heads up on what I can run

 

same as a stage 0.

 

yeah, the ,5 is the stage 0 just with tune

 

dont run more than 5 psi with bigger injectors.. a couple lbs isnt worth blowing your motor

 

0.5 could mean a wide range of things. I would call it a 0.5 if it had an intercooler. So, what exactly is running on your kit.


And HOLY Thread resurrection.

 

 

It has a huge intercooler and I run a tial 38 wg and a hks bov

 

do you have bigger injectors with a computer?

 

Not yet, that's why its a stage 0.5, if I did it would be a stage 1, but that's why I asked, because I am not running any management yet, I am having trouble locating some good 550 injectors...long story. But - am setting up my boost controller, so I put the small yellow spring in my wastegate, I thinl its 3.75 pounds, but I want to up the boost to what I can run until I get the emanage and injectors in.

Ok that being saidn didn't the og zpi stage 0 run 6 pounds out of the box, and isnkt true that I can run like 6\7 pounds due to the fact that I use only vp 100 octane and colder plugs.

 

dude, get a tial red spring its 5.8psi and thats perfect for untunned its what i ran, and then when u get tuned u can up it to 7 or 8, i say use the red because if u use the yellow u can only get 6psi outta that spring on a boostcontroller because its never a good ideal to double the wastgate boost

 

good idea

 

How you figure that?

 

hmm ... im running a red spring ..but 10 psi.. and its fine

 

travis its not reccomended to go over double the spring rate ie: 3psi spring x2=6

 

nice write up!
