2018 Camaro SS 1LE Baseline

Took the Camaro in to Superior Automotive for a baseline before doing any tuning or modding. Dyno was a Dynojet. Ambient temp ~84 degrees F. Humidity ~ 50%. Correction factor SAE. Made 403 RWHP and 404 RWTQ on pass #2 and made 404 RWHP and 408 RWTQ on the third pass. First pass not recorded/printed.
Their tuner, Tad, was very helpful. He datalogged the runs for me. PCM was pulling between 3-5 degrees of timing due to knock retard, thanks to California's wonderful 91 octane fuel. Time to tune.

Those are a bit low but that makes sense if you're getting knock already. Good luck with the tune, they should be able to wake it up. The factory really left some power on the table with these LT motors.

Dyno

No tune. No mods. No E85. Just run as received with 91 octane.

Tuned

So the car was tuned today at Excelsior Motorsports in Escondido. http://www.excelsiormotorsports.com/ The car baselined about the same as it did on Superior's Dynojet. Kushan did a 91 octane tune and we got the red line on the dyno sheet-396 HP/401 TQ with the engine hot. Then he drained out what was left of the 91 and put in the 14 gallons of E85 that I brought. Final numbers on E85 were 434 HP and 438 TQ. The only mods on the car are a Soler Performance throttle body and a flex fuel sensor kit. Overall I am happy with the tune. The car is noticeably quicker. Going to take the car back to Superior for a baseline just to see what kind of gains were achieved on the same dyno.

Took the car back to Superior Automotive to see where it is with the Soler Performance Throttle Body and an E85 tune, in order to compare it with the stock baseline. Picked up about 30 ft-lbs. of torque and 30 HP. Car was a little lean and behaving strangely above 6200 RPM. Fixed the fueling immediately, but the car is going to have to be retuned on a dyno to sort out the high RPM issue. Waiting on a Pray Ported intake manifold and Soler Performance 95mm throttle body before heading back to the dyno. Hoping to hit 450/450 when it is dialed in with the new mods.
Edit: After reviewing the datalogs, we found that the PCM was going into closed loop at ~6200 RPM. After reducing the PE Mode load threshold numbers a bit, the problem was resolved.
