dh,
hey guys,
This week I installed an hx40, 1200cc injectors and a new head gasket. I went out today to start tuning it and all was fine with just normal driving throttle percentages. In the low throttle %s, i went as far as 4600 rpms, 10 psi and 1178 maf hz. Once i had it all done and it was running good i was going to try tuning at half throttle and up but once i hit around 50% tp, it pulls all timing, goes rich and boggs down (turbo still spools higher though). I still have to boost leak test the car because i have not had time to make a tester but i was looking for other ideas to check while im working on it. thanks in advance guys! Log is attached (you can clearly see the tps go up and timing drop

For starters, I'd either revert back to the stock DA fuel/timing tables or drop in one of the Evo sets. Your tables are really extreme, especially the timing table.

I'd just start with a boost leak test. Leaks should be completely taken care of before you start tuning as they can throw everything off.

Make sure to take a look at this page and go through all the items. This will help us know the base line for the car as we troubleshoot problems so we don't have to keep asking/suggesting common things.

sounds good man, thanks! and the timing is a little high because im using the same settings as i did with e85 and my 20g but now with 1200s and hx40 but i will let you know asap on the boost leak test
