There is a lot of mixed reviews on it. One guy posted destroyed valves but he was making changes of a few degrees. I just adjusted a lil bit in a spot or 2 for smooth consistant power.

I would stay away from altering cam tables until more is researched. The VVT changes cam angles so quickly that you could completely wreck your valves like he did. At least, he stated they don't need to be changed until some parts are replaced with stronger ones, such as valve springs. The stock ones do not close the valves fast enough. He bent valves when he left off WOT because the cam angles adjusted and the valves didn't close in time.
summary: don't touch the cam tables.

I would vote downpipe over chargepipe! Ive made some really nice numbers with a stock car and with DP only as well! The CP is nice, but it didnt have AS much effect IMO.

That isnt exactly the tune I sell since that would be silly to post what I sell. Just some timing changes as well as dialing in the MAF tables etc... What's posted was a stock map I took and adjusted to show the changes. If you put those numbers in your tune and log it, then fine tune where needed, you will get similar results!
Make's 300ish to the wheels and over 355wtq on every car its been dyno'd on so far!

Awesome write-up! Nothing but useful info here. 
Is this tune set up for 91 or 93? If 93, do you have any suggestions on what to tweak to make it 91-friendly?

But 18* at .88 lambda is a good one as well!

With the box leaking I was getting KNOOOCK in the midrange (like 5-7*) with a .88 lambda and 20*
Back down to 17*(ho hum
) and more fuel(back to .85).
I think I may just leave it. I want the damn thing to last, and the KDWs are not up to the task of any kind of real throttle mashing.
I should play more, but I will have to with the intake install, which I despise MAF calibrations.
Wish you were up here. I would hand you some monies, and we'd go for a ride, I am that ******* lazy :rofl:

there is a few things i wouldn't change that you did. hence the spiked boost, and peaky dyno numbers. cranking the lower dal cells that you have done cause this. not my personal fav to do.
also the cam timing itself. the tables i run have yet to cause an issue with PTV {piston to valve} why is that? nothing in the part throttle range has changed. if you're conservative with it, you will make more power across the board.
aside from this? good info for the new people to start off with. once they figure out how easy they are to tune, they will see the light.
also. SMOOTHNESS is the key. rapid jumps in the dal's, torque management, fuel, and timing are destined for issues and hair pulling
