Finally went to the track tonight for the first time since I put my Hotcam kit in over a year and half ago. The car has felt a little down on power lately, but I didn't think it was too bad until tonight. Most of my runs were in the 14.1@ 102 vicinity, and my best run of the night was a 13. 844@104 with a 2.21 60'. I know that's not stellar driving on my part, but shouldn't it be faster than that?

If u got that 60ft time down to below 2 you would run a mid 13. Other then that I cant think of anything. Get some good traction and then we can go from there.

Trap speed is down an awful bit, Are you sure nothing is out of wack?

that seems not right if i can do that time at 7000 feet

I'm pretty sure something's outta wack; I just don't know where to start looking. I have a miss at idle that a new opti and the delteq/plugs and wires didn't even phase. Nor did adjusting the rockers several times. Could that be indicative of a much larger problem than I thought it was?

Try a compression test.

delteq should have fixed it assuming you have new plugs

Your car will not run right with the new cam until you get it tuned PERIOD! I highly recommend MadZ. I was running 13.17 @ 104 with bolt ons. I then installed an XE 224/230 cam and 2500 stall and was only running 13.11. After a custom program from madZ, (previously a hypertec program), I immediately jumped to 12.68 @ 109. After tweaking things more, I am running 12.30' @ 111. You have to get that thing tuned! Don't be discouraged yet. You do need to get some tires on that thing too!

His car is tuned. Sounds like some other problem to me. I'd also recommend doing a compression test.

May even be a broke valve spring. That woudl explain the miss.

Sorry,
I didn't read past the first part of the thread. I see that you have tuning done. It still sounds like an improper rocker adjustment even though you have tried re-adjustment several times. I think the earlier suggestion of a compression test is a good starting point.

Yeah...I did 13.9 stock...something ain't right!

change your fuel filter and check your injectors. they will definetly cause a miss.

They're both new. I changed the fuel filter when the miss began and the injectors just recently.

You might try hooking it up to a diagnostic scan tool. I am running faster than that with stock internals and a DA of 5000+.

I've got an AutoXray, but I can't find anything remotely out of the ordinary. It ran faster at the track after I removed the battery power for a few minutes, so I'm leaning toward a sensor of some sort. Today, when I was driving, I noticed that whenever the car was at idle or fully closed throttle at crusing RPM the left BLM quickly dropped to 108 but as soon as I got back on the gas it went right back up to around 128. What could cause that?
