Mods in sig. torque seems especially low. this was with the converter unlocked.
he said it looks like I have a very conservative tune(mail order) running a max of 22* degrees timing at WOT. he suggested a dyno tune and predicted about 15-20 whp gain, this sound right??



And I love dyno pics

It's hard to judge unlocked numbers

Mail order tunes suck imo.

Well the a/f ratio was nailed for sure. But the timing is weaken sauce

Unlocked can play havoc on dyno #'s. Just lock it on the next pulls.

I'm not a tune expert but A/F Ratio looks little lean !! 13.5 and 13.7 in mid range ??

Try 12.9 - 13.2 with more timing and locked I believe 330-340rwhp is possible.
My brother's A4 Z28 made 315rwhp only LS6 Intake and Air Lid.. (and yes I know stall takes some power on the dyno when its unlocked.))

Looks about right to me...307 unlocked should be at least 325ish locked possibly more for a vigilante. That's right in the ballpark for a lt/exhaust/lid auto IMO.

Maybe richen up the bottom end and put in more timing...

Might see 10rwhp from a tune. I wouldn't expect more than that.

You could probably get a few more from a little bit of timing and such.. HOWEVER.. Have you compared yours to a stock ls1 dyno graph.

Slowhawk

iTrader: (12)

Yes,if the A/F on that graph is right, it's too lean.

Looks like I will be getting a dyno tune

Fwiw my car with the mods in my signature only put down ~350rwhp and 320tq UNLOCKED

Unlocked numbers are often very shitty and deceiving from what I've seen...car traps 89mph almost 90mph in 2600+ DA with a race weight of 3740+# in the 1/8th mile.

Dude...your car breaks 8 seconds in a 1/8th mile at 3700 pounds???!!!!

I am extremely impressed. When my M6 swap in my Nova is done I have a dream of doing that after cam and such. Whats your 60 ft time?

Best is a 1.79 spinning still, best ET was a 7.85 but I lifted for a bracket race so my trap was bad bad low. That run was right after the pulley and dyno tune. 2680DA around that time.
