Nice car...

I think that 601whp pull is a software glitch... change the smoothing to 5 and see what you get. You will probably get around 570whp.

Nice job

Nice job
I had considered that. However, the smoothing is the same for both pulls and the blue run matches the actual dyno run. I used 2 for the smoothing because it made the blue run look almost identical to the actual dyno sheet. I was thinking more along the lines of heat soak on the intake temps on the dyno vs out on the road helping the top end. Intake temps got pretty hot toward the end of the pull on the dyno vs out on the road. We had just got back from lunch and forgot to switch the fans back on in front of the car for the pull. Haha. My friend has been out of town. I will do an actual pull to make sure in the next couple weeks. It certainly feels ridiculous. Haha. 4th gear on race gas feels like 3rd gear on my pump gas tune. Or at least close. Haha.

I also went back over the stretch of road I used to make sure there wasn't a dip or downhill slope at the end of the pull after seeing the graph. Just throwing that out there since it is dependant on the road for accurate numbers.

It looks like the curves follow very similar paths, with the red curve about 20HP higher throughout most of the run. I agree with Juan that the spike up at the end of the red curve is probably not legitimate. You can trim the upper RPM's with VD and then it looks like you're peaking around 560WHP on that run.

To check your logging/location for pulls I would do at least 3 runs or so. If they're all within ~5HP then you know what you're at. If they vary a lot then the location probably isn't a very good one or you're not doing it in the exact same spot each time.

Anyways, looks like a great setup! Car looks really strong above 5k. I think something like this would a great for strong top end while still keeping a reasonable powerband if you're not revving super high. Looks very nice.

I only changed a few cells of fuel and peak boost - peak torque timing. Which is why the gap is bigger before 6000 rpm vs after. The new run was where it should have been AFR wise in the weird looking section vs pig rich on the blue run. I'm sure that has a bit to do with it also. Oddly enough one of the dyno graphs from the "ams prototype intake" thread from this car has a similar jump in the same spot. This was on ams' dyno with their intake on the car.

No problem glad to see help pay off. Plus it's super easy helping someone who already knows what's going on.

I'll probably leave pump gas alone. Just in case. Haha. One day I might be brave enough to run 32ish psi and see 650-700...definitely going to need some sleeve reinforcement first though. I'm confident in the 580-600 whp range on my tune with race gas and stock sleeves though. Mainly because timing is half of what others consider safe. I couldn't imagine the numbers this thing would put out with 22-27* of timing. Lol.

im sure at the same boost levels its at now with hardly any timing changes if any at all i can make 500 with just fueling changes.

also the race gas power would be the same. no more boost than you have been running id just smooth out and lean out the afr's a bit. spool and power will wake up. no reason to risk the timing or boost when theres still plenty of safe power left

Ya. I do need to smooth out the afr in the spool area. I took the pump gas tune from 10.8 to 11.2. The map was super rich (10.1-10.5) during spool. When I get a chance, I'll send the cal over. I had to take a lot of fuel out of it. Haha.

Ya. I haven't had a chance to get it back out after making a few adjustments. It still needs fuel taken out. Haha. Still pretty rich during spool, but its much closer than it was. I'm having to do it as I can find time so its taking a little longer than usual. Haha.

Gotcha. It will probably be that long before I get it finished up anyways. Lol.
