Me and my father got our cars retuned yesterday,and the resultswere good in one way and disappointed in other way, my dad changed his set-up from TEA 1.5 heads and XE-R 224/224/.583/.583 and all the bolt-ons and SLP exhaust he put down 407rwhp,then he changed his set-up to trick flow 215cc heads and the 228/230 cam that came with the package deal, and he didn't inprove at all it was a 407rwhp and his car is m6 stock rear -end with 4.10's,and on the othere hand i got his heads and cam(look in sig of mods) the only differance between the to is mine is a a4,with slp coldair induction and bbk80mm tband my car put down 400rwhp,what went wrong with my dads set up or is there anything holding it back .

*scratches head* What was the difference in the day for the actual tunning?

Seems like the added duration, added lift, and better flowing heads would have lead to some solid gains. At least 15-20 maybe more. Not sure what up bro, but good luck figuring it out. Post up when if and when you find something.

Could you post and/or overlay your dads old graph with the new one?? That would also be a great help in figuring out what is up with the combo.

Sounds like you have a restriction somewhere. What intake does it have?

Also, was it retuned after the changes?

how much if any did the compression change with the swap? what are the rest of the mods on his car?

wouldnt the stock injector duty cycle be maxed for what hes running? i didnt think it took much to max our stockers.

I am with this guy!! The restriction could be the stock injectors. I made 423rwhp through a slipping A4 with a PTC 3600 stall converter and stock 3.23 gears. Tell him to throw a set of SVO 30lb injectors in there and see what it'll make..

ya that is what i was thinking esp. if it is a 99 which had the smallest of all the injectors.
