Guys, I don't post much but I read a lot! I think here on this board are some of the smartest people with experience from whom I have learned enough to have tuned my H/C car by myself.

I have a 408 GM LQ9 iron short-block going in and need some ballpark adjustments to a stock 2002 LS1 tune for initial fire-up. From everything I've read and heard, the first couple heat cycles are critical to seating the rings and all that. So I don't want to spend time dicking around with a stock LS1 tune to ballpark A/F and timing so the car will run right for break-in.

I already have done the calculations for IFR table and displacement/cyl. But need to know what adjustments to VE might help aside from the 60%-70%-80% in the low-RPM (400/800/1200 RPM columns). Or maybe other tables that that need adjusting.

Anyone out there can share some of their experience doing this right the first time?

I use LS1Edit for programming and EFILive v7 for scanning, but even if the info is in HP Tuners values, I'm sure it can be converted to LS1Edit values...Thanks guys.
