I need some help. I have a 2000 TA A4 3400 fuddle (unlock) slp intake, flowtech long tubes 3"y and catback. I made 297whp at 4800rpms on first dyno run but my fuel pump died. We upgraded fuel pump and then i only made 299.4whp at 6200 but at 4800 only 268. Im swapping out the TC for a full lock up because it feels like it slips a lot. Aside from that im going to do a compression test.
It was a mustang dyno.

I dont have it with me, i think i can post it later today. like power ramps up at 4000 rpms then plateas 5000-5500 and goes back up to peak 6200. It was tuned with efi live software, after i swap out TC ill get it redone. i think something is wrong with my car. exotic performance should know how to tune an ls1 they have several in the shop most of which have over 500whp.

I had exotic performance plus install the cam/valvetrain for me. i wanted it done right :-) Ill draw a picture of the graph from memory.
Drawing isnt perfect but gives you an idea. i only had like 243 tq at peak HP i think. My torque plummets after 5.

no it drives perfect. except when TC locks at like 50-55mph in overdrive. rpms below 1500 with no throttle it surges or bucks, ,but if rpms are low and im giving it gas it doesnt buck at all. no misfires, it seems to really haul *** when its like 50 degrees out. during hot day feels like it did before i put in that 3400 stall. Maybe its tuning... they said i had 311whp on the phone but when i got down there it only made 299... maybe they pulled some timing? i dont know...weird.

I wonder if the cam was installed correctly. 297 rwhp is stock or lower than stock. Did they give the factory cam back to you? Something is way off I would think you should be in the 350/380 rwhp range. I see you have long tubes and a 3 inch y. Which muffler did you go with? Are you still on your LS1 intake? Have you deleted air and egr? I dont think it is your fuddle. I bought a 3500 TCI and it took me awhile to get use to it. It felt like it slipped. I sent it back to TCI and had them make it a 4000. That felt like it slipped like heck also but I got use to it. Again I doubt your problem is the stall.

Its faster then it was thats for sure. but from what ive been reading a lot of people dyno 30whp lower when the TC is unlocked, my doesnt lock under WOT so i think that will help some. I also feel the tune is part of the problem. I made 297 at 4800 on first tune and now i make 268 at 4800.
299.4whp/296.7tq
Peak torque is at 4500
peak hp is 6020.
At the track i did a 13.9@102.9 BUT it was an awful launch i was still sideways at 50mph. I could of easily got a low 13 but i expected a much higher trap speed.

You have something seriously wrong as your track times and mph are seriously slow for your mods...i would bet that 90% of stock ls1 cars would have a faster time and higher mph than yours now and I'd expect you to be 50-80 hp better than stock.

Check if your transmission has too much tranny fluid in it. The first time i got my car dyno'ed after the cam it only put down 302 rwhp. It turned out it was over filled, when they drained the fluid to normal level it dynoed what was in my sig.
I did the tranny and cam at the same time.
