I had three dyno runs done with a 125 wet shot. The 1st two runs were done with the converter locked and the 3rd was done with it unlocked. There is about a 40 HP difference between the locked and unlocked runs. I have a 3400 Fuddle stall w/ 2.73 gears. No other mods except for exhaust cutout (on stock exhaust), lid, tranny cooler, TR6s, MSD wires, and DRs. I did not have any N/A runs done that day. I am guessing a N/A dyno for my car would show about 300 HP locked because it is an A4.

Does this graph show that I am blowing through the converter with the 125 shot or is a 40 HP difference normal with a 3400 stall? THANKS.

Its nice and flat. With a stock cam,manifolds,and intake it will be flat. the motor is not breathing well at that HP level with those mods it just reaches a max output and climbes slightly with rpm.

Which of the three mods you listed would help the most for the motor to breathe better? I really don't have the money to do all three mods. Thanks.

Ls1 intake or LS6? I think it would be a toss up for headers or an LS6. LS6 should be cheeper. If its an LS6 than do the headers. get a nice set of used ones to start with. I bought a $200 set of mac mids one time. after cleaning up the welds they worked good for a mild car.
