please chime in dyno #s...

99A4 TQ convertor/3.90s CAI (K&N)...Grizzly LTHrs

Dyno#s: 317rwhp / 341 Tq (1 yr ago)

Added 220-224 Cam and Stage II Lingenfelter Heads

Dyno#s 370rwhp / 375Tq (yesterday)

I was told that I would get between 360-390 rwhp. I was looking for 380+rwhp.

Now in Chicago yesterday it was warm 80+....I was told that at current temps the results could show 10-20 HP less than on a cooler day.

Would 80 degrees really make that much a differance than dynoing on a 60 degree day?

Do you think the GAIN and Numbers are decent? (gained 53RWHP and 34Tq with mild H/C package!

I have a bone stock '97 6 Speed. How much HP is a decent tune good for? W/O any modifications? Is it worth it to have it dyno-tuned while bone stock?

Your #'s sound fine for an A4 with a basic heads / cam package.

I don't see how the weather would account for a 20 hp variance.

SAE corrected hp numbers already take temperature into account. Those are good numbers. You would be hard pressed to feel the difference between 370 and 380 anyway, so just enjoy the added power!!!
