As the title states. For some reason, my car is on making 297 whp and 319 wheel torque. The shop I brought it to had never dyno a lexus before. Could that be the issue? Its also on a dynojet. Not sure what to think. Please chime in. Oil is new and full. Intake filter is only @ 2k miles. All runs were made in 6th gear. Car was on sport mode and traction is COMPLETELY turned off (pedal dance)
Mods:
RR-RACING ECU tune
Deleted ALL CATS
Custom 2.5 inch x pipe to borla mufflers full exhaust
RR-RACING AOS

Do you have the stock cats in the midpipe? Not sure if the exhaust you described is a full exhaust.
It could be a very low reading dyno, you should always want to take a baseline dyno run before the mods. You want to see the difference in numbers, not the final numbers since dynos can read high or low.
Did you break in the tune and mods as well?
that number seems wrong.

^^On the graph, I'm losing power top end for sure. It could be heat soak as my hood was closed and all 3 runs were pretty much running consistently. No cool off period. Yes, traction was Completely turned off and was in sport mode. I'm not sure if the dyno guy put it in M mode. Could it be from just using D mode and just using paddle shifters?

It's dumping fuel at the top end. It's close to 11:1 which is on the low end for even forced induction cars.
Your numbers are not corrected. Your barometric pressure is near sea level (29.92 inhg) and your IATs are lower than the correction factor although your humidity is higher (water takes up space that oxygen can't) so you should be seeing higher number. If I had to guess your car is pulling timing as it dumping fuel as well and it's all happening up high because your torque numbers are (even though they're lower than expected) higher than your HP numbers.

Jesus man, did they leave the parking brake on? LOL, I pulled similar numbers with my stock ISF when the operator accidentally left the E-Brake on for my first run. ![Egads!](https://www.clublexus.com/forums/images/smilies/pat.gif)
First the guy with zero gains on his Borla exhaust and now this..
LOL, I'm starting to lose faith in all dyno numbers recently, hah.

yep, it definitely is dumping fuel after 4k rpm.
