So I installed it!
Heres what happened
The car is at 8-9PSI
the a/f always stays at 11.8 at WOT
In first gear I saw 1.6 KR At 6296 RPMS & 13*
In second gear i saw 1.0 to 3.3 KR from 3976 to 5529 RPMS & timing from 14* to 9*
After I let go of the throttle
I see at 5000RPMS Timing going to 30.5 with KR of 4.7

Experts! Let me know! I have more info if needed

Mods are:
Intense stage 1 blower cam
Headers
Lites 104
180 tstat
Full 2 1/2 exhaust
Homemade FWI
 




The car was tuned for the 3.4 and was at 17* or 18*
And produced 260hp & 255tq with that set up

I wanted to try the 3.2 and see what happens

I cannot get a new tuner! He's the only one in Puerto Rico that tunes GM. :(
 
If you could only get 17-18* out of a 3.4 pulley and a cam, you're doing it wrong.

And you only made 260whp from that? The torque number surprises me more though. 255wtq?!
 
*facepalm "i wanted to try the (insert pulley size the car is NOT tuned for here) and see what happens"

it knocks, chips pistons, and gives you a sad face. just cuz you "should" be able to and it just slaps on doesnt mean you should do it...ever./end rant
 
go back to the 3.4 with more timing. whatever will leave you with AT LEAST stock timing (16*) and no KR is what you want.

its also too lean for a non-intercooled car. shoot for 11.4:1.

Click to expand...

I was thinking that as well. 11.8 on a non-intercooled car is lean to the point of diminishing returns.
 


Ok, I asked and at another forum they told me that It can be fixed if I had low kr with a tune. Now what would you guys have me do? He's the only one in the island who can tune these cars.

What numbers am I supposed to be seeing?
 
Ok, so im gonna change pulley tomorow

What numbers am I supposed to see with the 3.4?

And why is the torque bad?

What can I do for a better tuner???
 
I run a 3.4 on 1.9 Rockers/LS6 springs, Headers, and Autolite 104's, on 14-17* timing -- I make 250whp/275wtq on this setup..

Your numbers should be at the very least 20 more than what mine on both sides.
 


But i went to a mustang dyno and dynoed without the tune
233hp & 236tq

So what can I do for this tq thing?
And what can I do to tune?
The guy is the only one here! And its been known to be a good tuner!
But I dont know now!
