We took delivery of this 2015 Tahoe last week for a customer that wanted to unleash some untapped power from his new SUV :burnout:



This is our first Gen V Whipple system that we have installed, and we are thoroughly impressed with the performance and fit/finish of the system. Installation was straight forward, and took one day to complete. We also added some NGK spark plugs and our high-temperature spark plug wire insulators during install.



The result was a staggering 423rwhp / 424rwtq at 7.5psi!!!



For comparison, we pulled a graph from a customer's bone stock 2015 6.2L Silverado. As you can see, the Tahoe now outperforms the 6.2L tenfold. This was a gain of right at 100rwhp/100rwtq over stock for the 5.3L. Stock driveability was retained while upping the fun factor tremendously!



Stay tuned for updates as we look into further modifications with this system!

I'm sorry that a 130+rwhp increase with a 7psi supercharger on a stock truck isn't impressive to you, but there are very few systems that will give a 45% increase in power over stock. Very impressive to say the least.

so 10rwhp/70rwtq is the difference from a 5.3 to a 6.2?

Nice numbers!

40 rwhp if I'm reading this thread correctly.

I was going by the 100rwhp/100rwtq gains with 7.5lbs of boost.
423/424 - 100/100 = 323/324



Said 6.2 was 334/391. Thats what I gathered but I might be wrong.

Ah, I see what you mean. In the 4th post, he says it was a 130 rwhp gain, which is what I was basing my answer on. Now I'm confused, was it a 100 or a 130 rwhp gain? Lol
