You could go 3.4 without a wideband. But with the correct mods you're talking a 25% increase in power from stock. That needs to be accounted for and monitored in some way.
10-28-2011
i understand... any other mods you would consider before going to a 3.4 that i dont have... most pretty much told me what i need to run a 3.4 and thats what i bought and is what i have right now

Cold air intake or Fenderwell intake, and 1.9 Rockers+LS6/L76 springs.
Or a cam if you want to go that way instead of rockers.

That's what your high and low octane spark tables should look like before changing pullies. You want to go to engine-spark-advance to find that table.

Cruise timing looks a lil low there pal.
10-28-2011
it is, that is a random file i pulled up before my final tune was flashed
10-28-2011
My table looks nothing like that...
10-28-2011
what does yours look like then? Oh and how is that tuner working for you??Originally Posted by matt5112

This here is pretty good.

Something to do.
Car doesnt like 17* up top.
Stepping down to a 3.6 because it seems KR is there no matter what I do.
10-28-2011
I use the timing modifiers.
10-28-2011
I'd go to the 3.6 and see how it is when you retune it. Mine responded better with 19* on a 3.1" than 14* on a 2.9". What are your afr's at?Something to do.

11.0 flat.
To the OP, get a wideband.
Aim for 11.2 AFR and get it as flat as possible.
Then focus on timing.

Timing M90 car > Smaller pulley M90 car...proven as the smaller pulley gives you more low end TQ. but the timing give you the top end...which these cars lack in the first place...
I just can't understand why your car doesn't allow more timing with only a 3.4" with a full-size IC and headers...
10-28-2011
You forgot 1.9's.
10-28-2011
Even more reason? lol
10-28-2011
To be fair, the boost levels are kinda high.
7/7.5 to 9.5/10 on the 3.4
5.5/6 to 8/8.5 on the 3.6
10-28-2011
Meh, buddy had 12psi on a 3.4" with headers...ported heads would probably destroy that 10psi
10-28-2011
Its that or N/A (see stock).
Will decide over the winter...
