Not as much power than before with 99/00 head
What am i doing wrong. Can somebody look at my tune and datalog?
The car has a 99/00 engine swap on my original 94 swap. The head itself was rebuild, but just oem stuff nothing special. Car has Intake and exhaust.
According to my datalog my 80-120km/h is around 1,5 sec slower. My fastest before was 5,9s. And now its only around 7,4. I can also feel its slower

EDIT: I'm still learning into tuning with megasquirt

Yes, the timing was set with a timing light at 10 degrees, this was correct with the tunerstudio after trigger wizard. after that i started to change the timing table.
I can check it again to be sure
EDIT: The car runs fine, has nice idle etc

Cam timing is okey, i'm pretty sure.
I've got the problem, the problem is there are 2 marking dots on the pulley. one yellow, one white. I used the white one which was wrong.
Car seems to be fine now

I think some pulleys have a mark for 10*, and one that points at TDC when at 10*.
Always good to check that pulley mark too. Put a socket extension in #1 and find TDC, then make sure that mark points at the "T". They can slip.
