I finally got my Tahoe dyno'd and tuned. I only gained about 15hp on top of what I had when I came in. However, I had no idea what I had when I came in because I had not had my truck on a dyno since the radix install and the 4.10 gears. My last dyno with a Flowmaster muffler and a mail order tune (no radix) was 236hp/284tq.
I don't know what I had with the 6# pulley because I put on a 9# a couple weeks before this dyno run.
Anyway...I left today with a best 413rwhp/447rwtq. To say the least I was impressed. So was the tuner as he had to run it again to make sure the dyno was working right It was in the 90's during this sesion so I hope it will run stronger when it cools off. My injector duty cyle was a mere 128% on top (stock Z flex Fuel injectors, rumored to be 38/lbhr) Looks like new injectors are in order prior to the Nitrous Direct LS1 wet kit that arrived today.
MWAHAHAHAHA!!!

Thanks!! I would love to get this thing to a track. Only have a 1/8 mile that is close. I plan on going in the next few weeks. I want to get the bigger injectors and wet kit istalled and tweak the tune first.

(The Radix has a 9# pulley) Besides that...AirAid Intake. 4.10's/Eaton. Dyno Tune. Built 4L65E. That's it for performance. I have no idea why it made so much, I was expecting 300-320hp. I know when it gets to 8 and 9 pounds it is kinda scary the way it pulls and pulls and pulls. Maybe its a freak, built on a Wednesday??

Yep. I didnt feel like switching them back to stock. Plus then I would have to adjust the tune again later when I put them back on. Hell, I'm gonna run at the track just like it sits. 3rd row in, sub box, sittin on 24's, with the spare tire still mounted underneath. I wanna see what she'll do in FULL street trim.
