I'm surprised you added a UD Pulley short of a CAM installation. I would be looking for 400RW+ W M6 and 390+ with your full bolton AUTO inc that UD Pulley. Dennis and LS1LT1 ( Mark ) have gone into the 10's and
both have indicated they are under 400 RW. If you can turn 11.50 you know how to drive the Car. The addition of a PORTED FAST usually adds about 4MPH faster in the 1/4 and of course with the Tune it all comes to Life. The average DA's in the Northeast I think are comparable to
Da's in your Area. Good luck and keep the excitenent going. Leon

 

This is a great idea for a post. May I request an addition to what has been offered so far? What tires are you running on,A6 or MN6, Base or Z51 gears, Anything that would have been done to reduce weight or change suspension (better launch).If this request doesn't make sense than disregard, but I am thinking of HP (performance mods) getting down to the ground. Thanks.

Nice TQ number.

Did you have a tune also?

No tune?? This is the route im looking to go, but figured id need a tune with the headers
Also did u run the 1/4 yet with those mods?? What was ur times if so?
Thx

 

From what I understand you don't "need" a tune after that but you will prob throw codes without a tune. At least you are closer to ECS than I am. I'm getting the LG's (maybe ARH's after I call ECS tomorrow) this week and will be going to ECS next weekend or the weekend after to get my tune. Good luck with what you decide and go to ECS.

Yes it was tuned with the headers and cats and intake. I just think there was a little more in it. He tuned it to about 12.5 Air/fuel ratio I guess that is ok though. Just in case I get some bad gas some where it is still a lil rich. No enough to do any damage.

Would you believe my brother has an 08 like mine but an automatic 6 speed and he got 408 rwhp and 430 rwtq. Almost the same numbers as mine with exact same mods. I couldn't believe it.

Either the tuner just put in the same tune for both cars or I cant explain it.

 

No hadn't run in the quarter mile yet, but want to soon. I am running the indy 500 firestones in the rear. Keep in mind this is all with stock non npp exhaust in back on both mine and brothers cars. We want to get SLP Loudmouth 2 free flowing should pick up another 10 rwhp I think. The LS3 cars produce awsome numbers with minimal mods.Its just sick.(awsome).

I have the dyno graph but had a hard time posting it up on this site. The torque curve is like a mountain starts low then peaks high and low again. On LS1tech, you could just attach the file to your post dont know how to do it on this site though.

 

Any time you get headers and intake you should always get a tune. You dont want problems to develop later on with the combustion process. Too much fuel or too less of it.

I had to add the pulley due to being plagued with the bad LS2 pulley wobble....so I swapped it out before it took out the front of my motor

It was only 150 bucks for a shop to swap it.

I requested it be detuned due to my stock transmission

 

Better that you caught it now and if you changed it out might as well be
a 25% ud reduction. For that price I hope you got it PINNED. I know its extra work for the installer and my Mechanic said I dont need it because
I'm not supercharged. Glad I insisted and he did the Pinning for $75.00 extra. I hope you dont get any CEL's in charging system because you are at 600RPM with the stock CAM. In any event they claim about 5 -10 HP/TQ more with a UD. Good luck, Leon

 

No pinning (don't feel it's necessary) and no charging issues at all at stock idle speed with 25% underdrive.

The track has been closed the last 4 weeks for weather....so barring anything terrible coming through I should finally be able to make it out this Friday :P

 

Ok, I'll bite...Below is what has been done so far. LOL!!
