I directly contacted NST for it. It took a little while to make and ship, though. I know that Dezod now has 12PSI pulleys in stock, but I dont know how far you are willing to push it. Mine is right now back on a TRD reflash with no other tune. Its going to Dezod for that ASAP, though, but the A/F ratios look ok as is.

 

NST makes them special order!

Seeing everyone with the 9.5 pulley makes me want to go get one! but I have scared about blowing my motor!

 

But the 10.5 PSI was the limit you could do it on TRD reflash right ?
You have been using this Pulley for how long ?
any problems what so ever ?

 

I say 9.5 is the max you can run safely

 

Agreed.

 

but he has 10.5 on reflash.
do you have a Wideband ? you are monitoring right now ?

 

I have a UEGO hooked up and keep an eye on it. Honestly, It isnt like I take it up to redline much anymore, it really is a bit quicker than stock.

 

Just because he has 10.5 doesnt mean its safe.

 

UHMN OK .... well in redline makes the difference man !
it tends to lean in Redline ....
but i've heard till10.5 is the highest you can go with trd stock injectors !
but i don't know about the Tune...

 

Actually, my redline is when I see the richest a/f ratio... it is something like 11.5 at that point.

 

That is not that bad ... someone correct my if i'm wrong.
it's rich safe enough.
but till what RPM do you see that A/R ratio ? above 6000 RPM?

 

Yeah, its interesting, I am mid 12's all the way from 3000 to 6200 or so, then it dips to 11.5 for a second. Part throttle it does read pretty lean though (13's)

 

ohhh i understand ...
After 6200 RPM it dips to 11.5
i think you are at the edge there LOL.
be carefull.

 

Going to Dezod Thursday for tuning, Im playing with my F/IC right now actually.

 

Now I am looking for a basemap for a 9.5lb Supercharger with 550cc injectors. Anyone?? I know it's wishful thinking.

 

So how did the tuning go ?
any numbers ?

 

Hey, tuning went well. It was a street tune, and we have done 2 hours so far and it runs good on the 550cc injectors. I have a couple more spots I want to go back and clean up, but Dezod is great with the customers, and even better at what they do. Ill eventually find a dyno in the area, but I do plan on taking it to a 1/8 mile track Tuesday or Wednesday again.

 

^ so what kind of numbers did you finally put down?

 

^ LOL he just said he is lookin for a dyno in the area.
he has a street tune.
i am watching, would like to se what numbers it will put down.

 

^ so how many horsepower is it?
