Sorry didnt notice i havent been updating u guys. Tossed it on the dyno last night and before they mess with the vvt they wanted to run a crank relearn to make sure the ecu knows whats going on. I never could run crank relearn on my hpt it starts then just aborts. They try there modis scanner and it says the truck is in 1st going 158mph. My hpt scanner shows 158 mph at all times but the speedo reads correctly so i figure it was just an hpt issue. Guess not. So they researched all day but before messing with it they asked if i wanted them to keep working on it not knoing what the price might end up being or if i wanted to pick it up and look into it myself. I chose the later. They looked at my ve and maf table and said they look almost spot on just a little tweaking but with the ecu thinking its always going 158 then its pointless tuning for low end since its not actually going into the low end of tables and without the crank relearn the ecu might not have the camm positioning 100% correct.

Thanks for the great info. I noticed the thread in the conversion section regarding this: https://ls1tech.com/forums/conversio...t56-swaps.html Looks like HPT may have a solution for it here: http://www.hptuners.com/forum/showthread.php?t=36796

Thanks man. I found that last night through some other members going to try it out on my e67 and see of i can get it to work. Sent the guys at the tuners that thread this morning which brought up if i wanted them to muddle through it and see what happens or save the bill and work on it myself. That may fix the 158 issue but will it fix the other problem with the crank relearn that its saying its in 1st gear?

Finally got my truck and laptop back. Heres a pic my buddy sent me. Its the farthest the truck ever got. Atleast they could have made one pull to see where its at.
