just like u said, "Car feels strong when driving though, so I suppose that's what matters"

and yea, i had very high expectations and ted saw my frown when i got the numbers, but he assured me that he hasnt seen any high numbers with the same bolt ons as mine

ARH LT's, xpipe, cats = 30hp / .20 = 24
CAI intakes = 15hp / .20 = 12
tune = 20hp / .20 = 16
------------------------
total = 52rwhp + 320rwhp stock = 372

so i guess mines is right about there

Well there are always differences some L99 stock dyno 310wHP and some 330wHP.. Ted did a CAI shootout and the CAI gained 9wHP (if I remember right)
Dyno all read different. You can go to a dynojet somewhere and then it will dyno 398wHP.. What matters is how fast it is on the street or your trap speed at the track..

Interesting thread.... Given that I went 13.15@106.77 @ what, 4250 raceweight, that would with 20% drive train loss put me around 320rwhp stock.

Interesting to note 37x rwhp for Padre with bolt-ons, that was on a Dynojet?

MagnusKrans · 06-12-2012, 10:49 PM

The baseline pull was done with all the bolt-ons listed in my sig except the heads and cam, however I returned the tune to stock before giving them the car. I was pretty suprised at how low the baseline was with all that stuff on there, just goes to show how much a tune can bring out of those bolt-ons because I'm sure it was way higher than that with my jannetty tune on there. The car felt very strong before I got the heads and cam and well, just feels like an animal now. I can't wait to see what FI is like.

close...very close.

Oh yeah, I also forgot to mention my car only has 2000 miles on it, so maybe that could affect the numbers?

It looks like the real power comes from LTs. I know many people posted about gaining 20+ HP with high flow cats, but I'm beginning to doubt that works for everyone.

In my case, it's hard to know because I don't have an all stock baseline. Maybe I would've only pulled 310 stock...

Here is mine, before and after the TVS2300 and GM ported heads:

Before

After TVS, LG Exhaust:

Then, after the GM ported heads it went to

GQ4Life · 06-13-2012, 11:07 AM

My mods are Long tube,Cat,resonator delete,Flow master,Cold air intake,tune

Definitely talk to your tuner. It sounds like it needs some adjustments.

I'm done with mail order tunes, just not worth it.

I agree that I'd be cautious about letting someone tune my car via email, but there are a few sponsors on the forum that seem to do great work.

I dont have my dyno sheet, but I re-dynoed my car after installing the yank converter, and as I suspected, the tq read lower because of the loose converter (unlocked on dyno), but the peak power went up about 5hp which makes me believe the yank may be a little more efficient up top than I thought.

nighttowl · 06-21-2012, 06:03 PM

Here is mine. I installed everything on this car myself.

464 rwhp, 405 rwt
