badddd assssss. any drone though?

[primomarcelino]

Are those results from exhaust only? Did they tune as well? Sounds awesome.

[Dj0nes]

Zero drone. I was amazed. It was tuned yes. Only advanced timing 3 degrees and other parameters were adjusted as well forgive me I'm not 100% exactly what. Airflow, shift points and torque converter lockup ext. I'm sure more could be gained but I'm staying safe. This is just the first round more adjustments will come once I drive it more than 40 miles lol. These mods will cause no harm keeping her within normal daily driving. That sound tho.. It's hard to be nice haha.

 

Dynajet results-

 

 

Gained 30hp tuned for 91 octane. Yes, that's all I use.

nice gains, the improvement in driveability will be worth it. Heck the transmission tuning and torque management reduction alone are worth it.

[Willc11]

Sounds phenomenal! Ready for some 6.2L exhaust options.

Nice!! Looks like very nice gains. Your almost to 400 flywheel hp (393hp approximately)! And those Corsa tips are the best around! I'll be going a similar route with that tip style! Good stuff.

[Dj0nes]

Pretty sure Corsa offers a system for the 6.2 you should give them a call and see what's up. It worth the extra coin for zero drone. Also had the AFM programmed to only kick in after 45 mph** averaged 1.5 mpg more on my ride home vs heading out there. (40ish mile drive)

Did you just replace the muffler or did you remove resonators?

Nice job DJones! Very impressive numbers with a conservative tune and exhaust. I don't blame you for not advancing the timing but 3 degrees. Its nice that you have a great tuner within reasonable driving distance! Congrats on the mods!

Factoring in 22% drivetrain loss (I usually say 20% for autos but trucks got the long driveshaft and big wheels) you're more like 385 @ the motor, not bad!

[VMaxtastic]

Screw it.. I'm getting a Corsa cat back. Thanks for the video!

[Dj0nes]

Haha no problem Vmax. Since Corsa is local to me to there was a big rep at Smokey's while I was having it all done up and he said he'll post the vids on Corsa performance. Who knows when tho... Of all the cat backs I've heard thus far nothing compares. Price is steep yes.. But you pay for quality and most important Zero drone.

Like Chris said it's a cat back system. Flapper and resonator are removed. Soon I'll be deleting the 3rd cat to. No real reason it still needs to be around lol.
