Default Dynod today, oppinions?

So I got my car dyno'd today. Not very impressed but here are the mods:

RK sport Mid lengths, ORY, Flowmaster 80 series, CAI, 160* stat,TB bypass mod. Thats all I can think of for now, its an A4 car, dyno'd in 2nd due to limiter, so I know its a little low because 2nd isnt a 1:1. MY AFR was around 13.5:1 ish.

247.69 HP
283.91 TQ

It was done on a dynojet.SAE corrected.

Autos don't dyno well, my TA with Long tubes, ORYP, open Borla, Vigi 3200 made 270RWHP 302TQ on one dyno and on a different dyno made 266RWHP 286RWTQ, I could care less since it ran what it should.

Flywheel ratings are 275 hp/300 tq I think. Not too shabby, IMHO.

ditch the 80 series or install a cutout. That will hold you back with headers.

The cutout was open on the highest run. Unfortunately it wasnt done in my 1:1 gear so I know the #s are going to be off, anybody know by how much?

You're stock tune, so there's not much to expect really. IMO at least.

Its the stock KM I need to upgrade to an LT4 KM. Here are my near future mods:
LT4 KM, 52 mm TB, Adj. FP regulator. I hope that with those 3 things it will correct a LOT of the leaness.

you can find the lt4 KM's cheap on ebay,its not going to hurt. i always hear the auto guys saying to get an a4 stalled.

and do you guys think those factory flywheel hp/tq ratings are right on the money or underrated?

It does seem a little low because I did the same thing (2nd gear because of limiter) back when I was exhaust & intake and it was in the low 300's hp.
I even dynoed correctly (3rd gear) with the new 3200 stall and I made about what you made right there. I honestly can give a rats *** about dyno numbers. It's all about track times.
