Well got the truck up and running tonight! runs fine with 0 issues so far. swapped out to 60 lb. injectors also, most I was seeing was 60% IDC. Im running about 8 psi right now but it seems strong, and spools alittle quicker. Also the tune Allen sent wasn't as agressive, running about 16.5 total advance on the timing, where before I was running 18-20. Im sure upping it to around 18 will give it a huge jump in power. Im just gonna run it as is for right now before I decide to crank it up.

 

What kind of timing where you showing through nelson's tune through the 5.3? Just curious

 

I could get away with 18 deg. without any meth with the 5.3 @ 10 psi. @ 20 deg. I needed the meth. I know after the cam swap in the 5.3 going from 18-20 I made like 50 hp more.

 

Why up the timing dial in another pound or two, it will make a much bigger diff. then a degree or two of timing.

 

I know upping the boost helps but upping the timing helps alot also.

 

Good to hear the truck is running well!

I too noticed a huge difference when I went from 16 to 20 degrees of timing.

 

What are the other specs of your setup? I am thinking about some kind of FI in my wife's Yukon when I do the motor swap and I want smooth seemless power that she won't notice and will make good strong power. I just don't want to break the bank. I would like to see 450 wheel and I know a 450 wheel build on a NA setup would require alot better head, more cam, and more compression. I feel like 450whp with FI on a 370 would be a cake walk with a super mild cam and some mildly worked stock heads or even just a set of stock heads period. I also have a LS1 I might think about putting in there, since it is a highway vehicle and that reduced weight in the front end might help it ride a little better in the front. But buy the time I add whatever FI I want I will have offset the weight loss so it might not even be worth it. Please give me some more info on your build and goal power.

 

Glad to see it's running! you're right, lots of timing will make good power!

I ran my best with 5psi and lots of timing; 1 gallon of race gas and about 26degs of timing, yikes!

 

seemless power???? Sorry bud but the wife will notice it alot!!!

stock LQ4, LS6 cam, Trick Performance Turbo kit 7-8 psi for now, 60 lb. injectors , flt 4l65e lvl 5, 4" exhaust, and bunch of little crap that adds up to thousands

No goals right now just want to drive it and enjoy!

 

Thanks Allen! need to get some logs over to you for fine tuning
