![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I used the search and didnt find what I needed so here goes . Put in my LT&ORY now under a hard load it misses almost as it is on the rev limiter. took it to the track sat. and off the line from off idle to about 3k it would studder then pick up till it got to about 5k-5500 then it was like i hit the rev limiter
it would also do it when I was doing my burnout. I thought it was the plugs so I changed them yesterday but it still does it. need some help it ran great before I put in the headers and it also runs fine part throttle. list of what I have checked/ changed. new NGK tr55 gap .050, MSD wires 7ohm at 28-1 at 30 and-1at 27, all wires are on completly,now I am going to check fuel press. change fuel filter, and pull the codes... other info- race Pacesetters & thier ORY with sims in for the rear O2's . O2 ext. No burt wires all are well out of the way. SES light is on but just for the egr last i checked ( pulled the codes after LT went in) thanks

Needs a tune, mine used to do it back in the day (01') when I first put headers on.

anyone in know of a good shop in central Indiana? In between Dayton OH. and Indy. I checked the F.P. earlier it was ok at idle and droped just a bit when I first hit the throttle and came right back. havent got to check the codes yet.
