I just had my bone stock 2014 L83, gen v 5.3 dynod and it came in at 270 hp with a tune. I was like what?? Th engine claims 355 hp!
So then the tech said it is normal for a car to loose about 20-25% hp, and then I dug up the RIPP video on dyno pulls for a stock 3.8 JK and a stock pentastar, which show a 35% calculated power loss from rated flywheel hp to rear wheel hp.
I don't feel so bad now, my 3.8 made about 135 whp, and the pentastar a whopping 180 whp, but at 5,000 rpm! Anyone care to rev their pentastar to 5k? I do know my V8 is limited to 5,5k revs.....
