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

 

the sensor problem surely hurt ya and retarded your timing for sure..

 

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?

 

yes its close to where it should be, but it should be a lil higher

 

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

 

Filter is like new, just installed tr 55 plugs with ngk wires, oil is actually due for a change, 93 octane. haven't checked the fuel filter

just a little bummed with the work into it, its only at 335

 

I'd figure you'd be about 340ish at least... just sayin'.

 

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

 

Sounds realistic for an auto on a mustang. Dont forget its internet; everyone has a better rwhp than you and me..

 

I dont think its a dud, might suprise you.

 

was it a mail order tune or a dynotune?

 

dynotune, on a mustang dyno

 

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.

 

It's a A4, those numbers are solid.

 

Like everyone has said strong numbers for sure...don't be dissapointed...see what it puts down at the track

 

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.

 

well this all sounds reassuring, thanks guys!

and dirkdiggler, I can't wait to stall it. That's next at the same time as my gears
