Max advance for 5.3L H/C @ pump gas ?

Guys,

how much timing to max power have you tuned your 5.3L H/C 2wd RCSB NBS??

I'm pulling 23 max, but I'm looking to maximize power.

My bolt on 5.3 was seeing 28* with no KR.

I have seen as far as 35* no KR.

But I don't think that is the best ADV. for HP (nor tuning by KR only)

Did you ever Dyno your truck? If you did, was that the sweat spot?

I imagine a H/C and bolts on will benefit from a 31* Max wot or should 28-29* do the job?

I didn't ever dyno it. The butt meter said 28* was the sweet spot. I didn't feel like it gained any power over 28* and I felt like that was a safe spot.

cool, thanks PB.

Since this truck is H/C, I'll test 29*

It will make quite a few gain from the 23* I put b4

Last night this guy race a turbo opel astra and handed his butt !!!! :(

No way he'll catch him with 29* but a least will be less the flesh damage LOL

Truck is single leg, on street tires, so 1st and mid 2nd is fumes and smoke show !!!!
