If you're happy and the car runs great then that's all that matters. You'll def be low 12's with what you have when the air cools. Good luck!!

A 46 rwhp gain with just tuning is total BS. No way to sugar coat that. Some shenanigans are going on.

Im looking for the dyno sheet from my stock dyno. I believe it was a dyno jet. But let me find out. Brb

That's ok. You said you made 319 rwhp. That is on the low side. Typically the L99 will be around 330. So then you gained 27 rwhp with LT's and a cai. That's better bet still on the low side. Even without the tune but still closer to where it should be compare in relation to the other numbers. The gain of 46 rwhp with a tune only, in 98 degree heat, is ridiculous. A time will net you between 5-10 rwhp. It really just brings the mods together.

Here is the baseline (headers n intake w/o tunr) and the tune version.

Did they tell you what the Air/Fuel ratio was? Bc if it was 19+ go have your car retuned by someone that has a clue. I'm not sure what that "g" means after the AFR but that is about to blow up. A NA vehicle is around 12-12.5 wot.


No torque on this graph?

And yes it was a dynojet. Is there a difference between the dynojet and dyno dynamics??

Every single dyno is different. Even the same brands in different locations will be different to a point. Not crazy off.

Here is the hp/tq for the baseline

Ok. So wheres the AFR on this sheet? Why are the two dyno sheets showing different info? That's odd.

[1badbish]

Now i see the a/f for the tune spikes up but only after it lets off. Not sure about that but ill ask tomorrow. I was never really a dyno person so im still learning this

We are all leaning. That's a great idea. Ask the tuner about your AFR and simply ask why all the other L99's in the country average around 370 rwhp why is yours different. You paid good money so you deserve answers.

Gd luck!!

He gave me 3 sheets. One baseline hp/tq. One tuned hp/tq and one with just hp gain difference and a/f differences. I can get the a/f on both tho. Ill txt him tomorrow.

Good increase.
