Here's my Lund-tune-only dyno results.
I drove around for several days on 93 gas prior to dynoing with the factory tune. The factory tune dyno was 2 weeks prior to today's Lund tune results.
This is on the initial 93 file that Lund sent to me. I did send them 3rd and 4th gear WOT datalogs and they said they looked good, no alterations needed.
5th gear pull on each run.
Runfile 1 was a cooled-off (but 180 degree engine temp) factory-tune pull on 93 octane. Runfile 5 was a cooled-off (180 degree) pull with the Lund tune on 93. It did make a little more power. Runfile 6 was a backup pull with the Lund tune made around 5 minutes later, more torque because of the extra heat in the exhaust but it fell off back to factory hp at high rpm presumably because of heat soak from the factory intercooler being way too small for the car. Still, a robust gain overall from a simple tune change! Obviously the car feels totally different driving around with all the new low- and mid-range torque. 20psi boost at 2500 rising slightly to around 21.5 at the top of the pull.
Here's the weather condition / correction stuff.
