did the 5.3-6oh swap on my 01 ecsb back in september adn have been running the old tune till the past week
i found a vette builder/dyno tuner close by and got a tuning sesh
01 ECSB
04 LQ4 stock, AEM intake, catback 3" foot long glasspack dumps out the side in front of the rear tire, 4.56 gears 315-75-17 bfg AT 17x9 cragar soft 8's
60e with TCI 2nd/4th servos
circle d 28-3200 verter

the wheels weigh a slim 40lbs each
did the entire sesh in third gear, and could not get the dip out of it
then did a second gear pull on the same tune
got a video but thats not my department, waiting on my friend for it

here are the numbers
base line 244.9ftlb 196.9 hp
final 3rd 265.5ftlb 211.2 hp
2nd 262.9ftlb 258.2 hp

what are peoples thoughts on these numbers????

 

here is mine with just a few bolt ons:



The base line is all stock with:
- edelbrock shorty headers
- K&N FIPK
- Magna Flow Muffler Dumped

All Gains were in tuning.... Well Worth the $350
Third Gear Pull With Converter Locked

The fan Kicked On In The Middle of The Pull

About the truck...
05 1500HD, 6.0, 4l80E trans, 4x4, 4.10 gears, 6" Lift w/ 35" A/T's...

 

I think that's making decent power for 35's! And completly stock 6.0

 

Not really that bad. I'm surprised they spun it so high with the stock cam. What are your shift points? They should have started the graph around 3000 and ran to 6000 max.

Never heard of the shop and not to many places you see a Mainline dyno.

 

dude you have the dip in third too, but why are my third numbers so crappy, and the tuner was a vette guy, maybe that explains the high rpm run

i do not know the shift points,stock i think, i am going back monday cause the verter still cycles on the freeway, and i am gonna have him adjust the tranny shift times and the pressure

anyone know why my third numbers suck??????
i replaced the 2nd and 4th with TCI supers, and i think maybe the scarf cut seal may have gotten caught up,the first time i put it in it obviously didnt stay and got caught, soi put some sctch tape on the seal to hold it then slid the whole assembly in then pulled the tape out, but ever since i have been thinking about it
if the seal was messed up would it contribute to lower numbers?

 

i never heard of it either, but there is only one other place "the dyno shop"
that i found, and i heard bad things about them and they wanted 750 and 8-10hrs with it

the place i went to is a vette builder and he races, drag and road race, as well as build and r&d his own parts, the shop is full of customer vehicles
and he has not done too many trucks

whats wrong with a mainline dyno???????
i never heard of it before

 

ill post my dyno sheet after i pull it tomorrow
