hey i just finsh my project and its time for the tune. I have 06 silverado single cab 2wd with a 5.3 and a mt70 .68a/r front mount and i have a comp cam 222/224 566/568 lift for right now with 112lsa. and and i installed a 3000 converter and fmic with stage 1 snow performance boost cooler and
60lb/hr. injectors with 3.73 gears so what would be best way to tune my truck i dont really know i will take it some where for the tune . But i think theyr like a sd tune 2 bar or something else so i should leave my MAF sensor or what do you all recomend me to ask my tuner . and i wast 10psi - 11.5 psi should i be able to make close to 500rwh with this set up and what should i run in 1/4 more less, thank you for you help !!!!! and also i have a 255walbro fuel pump in tank and do i need a fuel regulator also and what kind .

 

I started out with a Nelson tune, and I was really supprised at how close the tune was. I still have the MAFS. My tune was on the rich side , and timing is on the low side. So I just turned up the boost until AFR was 11.5 @ WOT. That seems to be about 13psi @ my elevation. 15psi gets me 12.2AFR, 10psi is 10AFR etc. Injector duity cycle is around 72% with 68LB injectors. I have a new tune ready, with some minor adjustments made. I hope to try it next week when I get back home to Co.

 

your setup s pretty close to mine. im running 10 psi, ls6 cam and 3000 TC. Nelson tuned mine and it runs stong. A/F is high 10's to low 11's. I think you will be very happy with Nelsons tune.

Im also running very close to 500 hp. once my efans are on there I should be there, either that or stock tire will put me there
