Question Does this sound about right for power?

2000 Trans am A4
When I first dynoed the car all it had on was a borla-non adjustable catback. With a misfiring issue do to a cam sensor.
car made: 280 hp 290 tq

Now it has 1 3/4 long tubes, ORY, LM2 catback, Lid/k&n, P&P TB, ls6 intake, and a tune

it made 335hp and 340tq
So it looks like it gained 55 hp and 50 tq

Does all of that add up to be about right for what went into it and is it safe to say my car is somewhat of a "dud" with a low baseline

yeah for sure, with that fixed though, assuming the power would go back up to around 300 stock, shouldn't I be seeing higher numbers with everything added and the timing fixed?

might sound stupid but uh, how does ur fuel filter look? Air filter? Plugs? Oil? Proper Gasoline Octane? Trans fluid? might be bogging it down

I would say it's not too low. It is a auto. Underdrive pulley and stall and run mid12's easy

I say that's really good for the mods...my car made 290/289 with a lid, catback, underdrive pulley, ls1intake, CAI, and 3600 converter.

314/314 after header install and Y

My best e.t. is 12.47 @109 with 2.73's

ah i see, yeah the tuner said he's seen variations anywhere from 30 hp less to even 30hp more than where I'm at so it really depends on the car

this was on a mustang dyno too, so probably more realistic than a dynojet so ive heard

either way i'm taking it to the track in a couple of weeks, excited to see what it puts down

Those numbers are right on for what you have done, I put down 330/330 with pretty much same mods on his dyno. Put a stall in it and it will be a different car. Don did a yank 3600 in my car and it was best mod I've done so far.

Numbers look good with regard to a loaded dyno and being an A4. Have fun with her OP!

well, the dyno did show a positive gain from the mods. as long as it traps 109+ i'd be happy with it.
