doesn't really matter. both do great work and are about the same price.

 

how much HP do tunes give u?

 

since your an A4 car The best bang to the buck would a stall converter and gears. A 2800-3200 stall and 3.73's will make a heck of alot more difference than headers and CIA and underdrive pullies. I went from a 2400 stall to a 3500 stall a few years back and picked up a half a second just by changing converters. Just my 2 cents.

anyone have any head work done?

 

I went that route. I went from pocket ported Iron heads and a ZZ3 cam with a 1.5/1.6 roller rocker mix to well ported AFR 190 heads and a Hotcam and 1.6 pro mags. For 2500 dollars I gained a whole 1 tenths of a second. I gained the most out of the converter and gear change.

 

I forgot how much the tune was..

but i have a 2400 stall and 3.73s

definitly two of the best mods i have done.

 

man no one knows the $ for the tune lol

 

does anyone have a used PC with a tune???

 

I think pcmforless does a 175+shipping, he sends you a "used" pcm with the new tune on it, and you send your pcm in to him(for your deposit back). or there is a load it yourself one for $75. He custom calibrates the tune for your mods, and wants, so a pre tuned computer is not the best route.

 

i didnt even think about that

 

Go to MadZ28.com and read it over. He lays it all out for you quite nicely. There is a FAQ there as well. I was very pleased.

 

do the 160 t-stats lower the engine temperature to where its not at optimum temperature for the most power/efficiency?

 

i already got it
