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

Was tuned in a dyno near home.
What do you mean by not enough timing???
11-08-2011
It means you're running garbage for timing at your pulley size and AFR.
Get a new tuner.
11-08-2011
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.
11-08-2011
I was thinking that as well. 11.8 on a non-intercooled car is lean to the point of diminishing returns.
11-08-2011
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?
11-08-2011
you need to richen it up and add timing. whatever pulley you can run with those is what you want.
11-08-2011
You were tuned for the 3.4....Run the 3.4
If you want to run a 3.2, get tuned for it.
You should be able to run 19* timing on that 3.2 at 11.4 AFR
11-08-2011
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???
11-08-2011
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.
11-08-2011
just cuz he can tune them...doesnt mean he CAN tune them
11-08-2011
Ummm, so whats wrong then?
Why is the tq so low?
Whats going on?
11-08-2011
The dyno isnt reading tq right probably is all it is.
11-08-2011
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!
