never had it on a dyno to test it i mean it feels like it has alot more go to it but at the track its just not there havent got anyone around here with a lap top to hook up to it to see whats going on in the runs no codes or nothing

I just had the same thing , I ran 13.01 @ 109 with a loudmouth , asp pulley and fipk on 18" street tires. I installes a mti S II cam, kooks long tubes, kooks catted Y and meizere ewp and ran a best of 13.80 @ 103 mph .

Turns out I had a bad knock sensor giving me a whopping 9 degrees of timing wot plus It fukked up my o2's missfirring ( best guess ) so I was running one bank lean and the other rich and everything was crazy messed up

Anyways look for knock . . . . any trouble codes ?? Ive still got a messy o2 but just fixing the knock sensor has brought her back to life BIGTIME

You need to monitor the engine on atap, get it on a dyno or something. Only that can answer your question. That should have been done before it ever went on the strip. Or the road, for that matter. You have to know what the engine is doing or you can kill it, do it right man. Just slapping on mods and racing it is asking for disaster.

did you tune on the track? How did you tune without a dyno? Also ported MAFs suck I picked up 18RWHP going back to stock descreened

RJF

it was tuned sitting in my driveway drove it for 500 miles everything fine changed oil filled her up with gas and put the et streets on

i bought me an obdII scanner at advanced auto to scan for trouble codes going to go do that now.Anyone on the boards from around indiana? that has something we could test? im open for ideas.Another bad thing is the tuner that tunes my car is real bizzy.Im thinking about just send the pcm to TSP and let them tune it.

RJF

well found 3 codes on of them is the same one thrown twice P0113 IAT Sensor High imput it was thrown twice next is a P0300 Random Cylinder misfires.Also Im running tr6 plugs for n2o as i was running last year should i change plug since im not spraying till i get injectors?

JoeDirt

Intake Air Temp senor , check the connection. . . thats an important one for getting your mix right .

P0300 is comon when a cams installed , I was getting this with the bad knosk sensor , now with that fixed its smooth and no p0300 code. Your cam is much bigger but fixing the IAC should help . If the pcm doesnt know the temp of the ar its breathing it cant adjust properly.

I ditched my TR6's for Irridums and noticed an improvement off the sauce. I could open my gaps back up too

Best is to autotap it . . . your air fuel might be messed up . . . . if it was anything like mine
Hope it helps.

anyone else have any info do you guys think that buy having the ls1 intake its restricting it so much?
