Guys, come on, you're boosting DemonSilverdo's thread. He didn't want the 5.3 vs. 4.8 debate, just the 4.8 numbers. 5.3's are more powerful, that's a fact we all know. You throw two trucks with equal specs(weight, configuration gears), one with a 5.3 and one with a 4.8 the 5.3 should beat them. By how much is the topic for another thread (or better yet a video). Let's get back to the 4.8 number discussion. I am curious how he could be losing over 30% through the drivetrain. What can he do to check or tune it up?

Last night a Famoso Race Way my little 4.8L beat a whipple charged 5.3. Oh My God, is the world going to end? A 4.8 with a beter driver is beating a poor driver with more motor.

how big is your shot golden?

DemonSilverado

Thank you very much. I asked nicely not to have my thread hijacked.

I'm sick of hearing who can beat what...I DONT CARE.

All I want to know is how i'm losing so much power, with my TQ being so high. And how I can fix it.

I have decided that detonation may be a factor...

The soloutions I have been given are to run higher octane gas and change the T-Stat.

So my plan now is to have Lyndon re-program the PCM for 93 (currently at 91) octane, and run 93 octane with a small octane booster. And i'm going to swawp out the T-Stat, my question is...

What temp T-Stat should I switch to?????

Thanks in advance for your help and for ending the trash talk in this thread.

This small ***** syndrome is never ending.... Happey trolling Thunder....

Slowverado

well, the tstat thing is up to you, just depends on how cool you want your truck to run. i have a 180 in mine and it never ever gets above 180 no matter what kind of traffic i'm in or how i'm driving or anything. i have no problems at all. if you were losing HORSEPOWER due to detonation you would also be losing TORQUE so that's probably not your problem.

DemonSilverado

I had the same thoughts. But I cant come up with any other answers. I think i'll proally go with the 180 T-Stat.

Swapping the T-Stat won't have any negative effects will it? I mean if there is nothing negative, I might as well do it just to eliminate that problem.

If anyone around central OK has a scanner let me know i'd be happy to send some cash your way if you'll let me use it to try to diagnose the problem.

At/about 60HP. The track was very slipery and I just out drove the guy, the throttle has more then just off and on especially whith poor traction. His truck was also a heavier x-cab, wideside, and a system. I had about 600lbs on him.
