and my results were 152.8HP and 298.5 TQ and this was on my 01 silverado with a 4.3 and freemods and pullies only not to bad i guess what do you all think

 

You got 298.5 rwtq out of that thing? If so thats amazing.

 

that's less than 10 away from my majorly modded 5.3, knew I should have gotten the 4.3!

 

OK, i love the 4.3 and all, but i think the 298.5 tq was a typo. The 152.8 also seems a little low. I would think it would be more in the mid 160's-170's.

Please post up the dyno or set me strait.

 

I would think it would be more like 198 tq. ?

 

most likely thats it. The stock specs are 200hp/260tq. And i dont think there as under-rated as the 4.8/5.3's.

They is what they is. lol

 

ill go by the shop tommrow if i get time tommrow i know the horsepower is rite but they were having to do second gear pulls on the dyno due to the speed limiter so the torque was showing 347 and they said it was about 30% less than that so it would be 242 did my math wrong earlier but when iget the truck tuned and the speed limiter gone ill check it again and yeah i was kind of dissapointed with the HP it was hot and but still i have a ported throttle body and underdrives on it and opened air box

 

hmm, I still think the torque is a bit high, isn't there a 20% drivetrain loss? and if so then if the engine is rated at 260tq it'd be around 208rwtq. correct me if I'm wrong.

 

i agree like i said im sure its off im not standing behind that number saying thats what it does

 

I dont think 242rwtq is out of the question for a 4.3. They are pretty well known for awsome TQ.
