you need a dyno tune, a mail order tune from texas speed wont help much

after my dyno, the car ran great. Before I had to drive with two feet to keep the car from stalling at idle. A mail order tune is just enough to get the thing started without hurting anything. As for your smoke issue im not sure. Did you install yourself? We did my install in the garage and never had any kind of smoke issue. How long has it been smoking?

has it been consuming coolant or oil?

i hope so i need to get this thing figured out i hate stopping and the car is idling at 2k at a red light

Are you losing coolant? Sounds like it could be a head gasket, have you checked the oil?

jocko

i was thinking head gasket also so i would check coolant and oil for mixture.

what head gaskets did you use? When i installed my combo TSP sent me the GRAPHITE gaskets and was told the 5.3 heads will leak with the MLS gaskets.

the coolant level is the same and the oil is the same also i used the graphite ones they sent to me it only does this when i first start it then it goes away

Not all 5.3l heads require the graphite gasket, it depends on the heads. Did you check the rocker arm bolts & seal them? Also how's your breathing configured?

From a tune perspective it should be pretty easy to get the tuning lined out. Is it tripping any codes? WHat IAC counts are you seeing? Any ideas on fuel trims & the condition of the o2s?>

i have yet to pull anything apart again but i followed ls1howto.com for the install. i thought on the rocker arms u just torqued them down. i a slp lid and everything else is stock. i dont get any codes and i dont have the stuff to monitor any of the conditions

The intake rocker bolts need ARP type sealant on the treads,the bolts holes after porting protrude into the runners.

jocko

what type of sealant are we talking about here?that is why i have a scanmaster and hp tuners so i can monitor but you can always buy a scanner or borrow one from a buddy,a regular obd2 diagnostic scanner sometimes will allow you to see live data.

its a moly type lube, any high temp sealant should work though

i put thread lock on them when i put them back on

Threadlock will do fine. How long ago did you do the swap/miles?
