I'm trying to guess how much power to the wheels I'm makin.. I have a tune scheduled but before I go I was just wondering if anyone has been tuned with the same mods as me.. I currently have a lpe cai, kooks 1 3/4 headers with highflow cats and a muffler delete.. anyone been tuned with a simalar setup? If so what did you do to the wheels? I'm hoping to get into the 380 to 385 area but who knows.

The CAI won't get you squat.

My LS6 went from about 320-325 to 350 rwhp (DynoJet) with headers and a tune.

An LS2 will be higher, but you'll need a modestly more aggressive cam to get you to the 380-385 area, even in an LS2.

Just my $0.02, mind you.

Sounds like about where the LS2s start out. Darn truck engines really put out the power.

babrown18

Lol.. I hope I see some decent numbers..

rand49er

You'll see very good numbers.

Any more performance mods planned?

LS2 - 382 RWHP - kooks 1 3/4 catless, magnaflows, & cai

EDIT: J/k. Darn Jason's car must be an outlier.

Hell yeah.. thanks.. yeah when I get the money ima let east coast supercharging cam it for me.. they say that they guarantee a 100 hp gain.. but we shall see lol

I was 375/368 on a dyno jet with K&N cai, Kooks 1 3/4, off road pipes, and magnaflow with tune.

my guess is 370rwhp with the weather being as hot and humid as it is it may be less to be honest, the LPE and K&N intakes are so prone to heat soak its not even funny. Itll feel quick as **** at nighttime, then 2pm the next day itll feel like a complete turd trust me.

I wasnt thinking about the weather. My numbers were on a cool spring morning. I would guess low to mid 360's with all the humidity.

I agree...it may not feel really quick now, but wait till the weather cools down. Damn!

yep mid 90s and 100% humidity all this week, **** sucks for the cars feels liek 285hp during the day and 400 at night time its insane.

Cool.. maybe ill wait until the fall to do in then lol.. yeah I know what u mean about the day and night difference with the humidity. I've noticed it already.. my v pulls like a **** @ night, but in the day with all the humidity its like wtf

serik21

380 is realistic ditch the cia, i got ls6 tune and exhaust 365, my buddy with pacssetter headers.ls2, corsa exhaust tune 384 dyno jet

whisler151

Definitely do the tune now. A summer tune is not bad at all. I'd rather be tuned in 102 and humid then tuned at 60 and dry. You know that your car will preform perfectly in all weather conditions.

Dont give too much thought to the dyno numbers. Get a good tune now and if you want bragging numbers go to the dyno when it cools down.

Thanks for the insight bro..

Aw ****, Brandon's stepping up to the big leagues!

For dynos:
Keep in mind people, that humidity along with pressure, and temp are adjusted in your graph when using STD or SAE correction factors... you should end up with the same curve no matter what 'humidity' and let the correction factor correct for it...
so eliminate the weather variance...

Focus on the tune variances, if your tuner is smart to tune when oil temp is at optimum for example or to ensure that IAT Bias curve is not too far out of whack.

You can see the values in STONE17's post.

Read the above post... with correction factor taking in humidity, it doesnt matter on the dyno. (remember... correction is bringing the curve and numbers you see to a DRY SEA level reference point. Loop up j1349 standard Automotive Engineering.

The dynojet has a pod that measures humidity, pressure and ambient temperature...

If you guys want to see the REAL temperature variances, you guys should be asking for an UNCORRECTED sheet as well, during your dyno runs...
those are the True numbers on the ground at that time, that air content that day...
