I wish I had dyno'ed my SS, before I installed the free flowing muffler, and installed the Trifecia tune.
Vince at Trifecia, said to expect around 50HP, and after driving the tune for a week and a half, and wringing her out[a lot-it's so much fun!], I can believe a 50 HP gain. Being a ole ex racer, and being real subjective about HP and torque gains thats advertised, I can believe it.
This puppy will blow the tires at anything under 50mph, with traction control on, and pulls so much harder than stock. No dyno's close by, but in a couple of months, will try and dyno HP, that I have now. I know it's a bunch.
I've ridden in a Stage 1 tune, and I can tell mine pulls a lot harder[no joke].
Seeing a steady 24lbs boost[as per my instructions to vince]. Using stock piping and did'nt want to blow the piping up.
I'm real happy with what I got. Already handed a couple of guys their ass, including a buddy of mines new Camero[up to around 90mph, from a 40 mph rolling start]. He was impressed, and said " I could hear your tires spinning as you blew by me]. This is no fairy tale folks. Every time I drive her, I get this Shi-ing eating grin, when I jump on it. I see tires in my future.
Thats my story, and I'm sticking to it. "Moon"

Ya, I will get right on that!
I never claimed to be speed racer, just offering up my baseline.
I am sure I could see 13's with better tires.
I have also changed out my intake and exhaust since the last time I went to the track, so maybe in the spring I will install the roll cage.

SPPD, not knockin' or yappin' your #'s! All this just adds to the crap that I throw at one of my older brothers 'bout these little hotrods. He doesn't believe the SS is able to out run most of his mid 60's muscle car collection. I personally have out ran his 65 Nova with a zz4 block, chopped rear blah blah blah. (Yea the one I'm tryin' to buy from him) the comment 'bout the bar....you know.....track officials etc.....And d@mn, ya'll puttin' down some good quarter times for a station wagon.

The ADVERTISED rating is 260, but Steve's stock output is way below what would be expected from 260hp at the crank with the high efficiency we have on our cars. I would have expected to see more like 240hp to the wheels, but it is dependent on the type of dyno used as well as other factors...
Also, couldn't remember if Steve's was manual or auto. The autos are much less stock...
