Just finished my buget build on my 2001 Z28 A4.
LQ4 with stock 317 heads, ASA cam, LS6 springs, LT headers with o/r ypipe, and 3200 stall.

Numbers are 354rwhp 353rwtq
The tune was done on a Mustang dyno and I know the stall and A4 will rob some power. It just seems low to me, I was expecting around 380ish.

The car really feels strong and drives well.

I have always heard that mustang dynos read lower, but what really matters is the performance, dyno numbers are just that, what intake, cam size, any work done to the heads, these are some big contributing factors. If you had a 225ish-230ish cam, ported heads, and a fast intake, then yes those numbers are low. But if its a small cam, Ls1 or LS6 intake, and stock heads those numbers seem about right. Just my 2 cents.

The cam is a low-lift cam. 226in 236exh .525 lift 110LSA. Stock untouched 317 heads and LS6 intake.

Got a print out of the dyno run?
I would say they seem a tad low. but 243 heads will make a big difference.
I had the same setup on a stock 4.8 with boltons and a nitrous tune.
Got me about 320whp 300tq. One thing I can say is the cam loves open exhaust. The less restrictive the better. Budget fo sho. I paid $150 for a new asa cam and $50 for the valve springs.

Not bad for the mods and dyno.

If you have the money, find a dyno jet to see what it puts down, I'd guess around 380-390.

You have to remember, your an auto and have a 3200 stall.

The big question -was the converter locked?That can make a huge difference in the hp/tq #.

OUTLWZ

Converter was unlocked.
Ill post the print out shortly.

Car drives really well and pulls like a motha

I wouldn't worry. For and unlocked converter, on a mustang dyno, those are good numbers. Lock the converter and put it on a dynojet and it would do 400.

What he said..

DO you by chance have an idle clip for us? I always wanted to move that cam to my 6.0... but didnt get the chance.
