Vengeance 224/112 stalled A4 with cats. Short story: 95F heat; 378rwhp and 370rwtq with basic boltons through cats (see sig). (the lower graph is a slipping trans) Previous dynos were 317/317 a year ago. The trans may have been slipping then. And several years before that it dynoed 322/342 before the converter and intake. Either way the gains are impressive.
Long story…after all the reading and emails between guys on the board I decided on a 224 type cam. If I didn’t have 125,000 miles on the block I would have gone with the FM13, but I didn’t want to wind it that high. The car is a daily driver and I wanted the power in by 6200. Anyways I took the car to Vengeance for the installation. Besides the 224/112 cam they also put on a set of 241 heads with 918 springs and stock retainers. I considered a better set of heads, but I wanted to save the money for the transmission. I figured I had several thousand miles left in it not less than 10... Vengeance couldn’t get a good pull after installing the cam because the extra power pushed the trans over the edge and it slipped badly in 3rd. Ron saved me a lot time and cash by putting in a stock low mileage trans. The car was turned around quickly each time.
Vengeance Racing’s customer service is top notch! Here’s a great example, Ron lent me his personal vehicle for day so they could work out cold start and converter lockup problems. I couldn’t drive an hour and have the PCM tweaked for cold starts with a hot engine…
PS one other guy who deserves credit and does all of the heavy lifting is Buddy. While Ron’s on the phone and Mike’s on the computer, Buddy’s bolting together these great combos.

Congrats on your numbers with your new setup 
I continue to hear good things about the guys over at Vengeance... I'm actually going over there next week to have some gears installed.
Maybe one day I'll be putting down some numbers similar to yours if I can ever get around to getting my stuff out the garage and installed

Just to clarify Torqued only paid 200.00 for a set of 241 castings.. While in your mind it may be a waste of money.... Any car with 150,000+ miles and junk 98 castings WILL benefit from a BRAND NEW 2002 casting with zero mileage.
