Re: Anyone ever dyno their 4.8's ??? (Stock or Not)
I made 251 RWHP with K&N FIPK2 intake, cat-back exhaust, and a Hypertech programmer.
Deamon, I think you got boned on the dyno. I have never seen even a stock 4.8 dyno below 220rwhp.
Note to everyone
He has nicely asked SEVERAL TIMES to not make this into a 4.8 vs 5.3 thread. Future posts to that effect will get deleted. Hyperlite...if you feel you need to comment on this, start a new thread or PM me with a response.
Thank you for putting a stop to the extraneous posts as well.

Slight change in plans. Lyndon didnt think the Z06 MAF would do anything for me, and since he can take into account the fact that mine is de-screened I'm gonna stick with the stock MAF de-screened.
Still goin with the 180 T-Stat and gonna take it to another shop for a different dyno. This time i'm gonna run the A/F ratio and the Wideband.
I'll keep ya'll posted.

Yup yup that would be me and the ladies bone stock 4.8 on there. went and ran a 15.9 the weekend after in it with no weight reduction. Thats all the poor truck has still minus exterior mods. And ill vouch for Kurts pass on the dyno where he put down only 1 more HP then us 
with more mods 
Im still around just my focus has moved to another car

I'm seriously hoping that when I get the rest of this done the numbers come around to where they should be.
