So, Rick (SynergyMotorsports) just called with some mid-tuning result. I wont say how much until he's finished but it's making more than i expected.

With all the mods in my sig and making 7lbs. at the top, how much hp do you think i'll make. Oh, it's about 80* with 43* humidity.

 

I would say about 460-470..Buddy of mine in Orlando was running 8 psi on the radix and 5.3L with a bumpstick.. and dyno'ing 474....

 

Well that would be amazing but according to The Dyno Truck List the best 5.3L Radix'd 4x4 truck makes 440hp.

 

i say 425 and 440tq

 

Damn the power 80 degrees and 43% humidity damn i'm in florida and it's 100 degrees and like 100000000% humidity

I say 430 hp and 440 ish torque

 

I say 465-475 ish.

 

Hehe..I agree with Blown Chevy...

Hmmm I think that he is a member here and I have seen his dyno sheet... I believe a quick pm to BigBlackAv will quelch your sceptism..... In fact I think I have a copy of his dyno sheet.. we are members of the same truck club ...his first dyno was a measley 434 rwhp... then he got a good tune...hehe..with that 434 rwhp he turned a 13.6 1/4 in a 5800 lb 4x4...

And as for your "it can't be", because it's not on the Dyno Truck List thought process..... Just because it is not on that list doesn't make it so... BTW I don't post to that list either and yet my 500+ rwhp dyno sheets are all over the internet...

I stand by my posting.....


edit for spelling

 

I know not everyone posts to the dyno list, i used it as a guide, an averaging of mods/power. My mods are pretty tame compared to a lot of others too.
I know my Tuner know his sh*t and is working hard on my tune.He worked all day today and We're not finished tuning yet , about another hour of WOT pulls and some fine tuning on the street tomorrow.

 

Hehe...it's all good....

Good Luck with the buildout....

 

435/455...ending somewhere around 450/470
