I just finish my lsvtec engine two weeks ago and so far I have put 200 miles on it.
I got a b16 head with skunk2 valve springs and retainers and stage 2 cams with cam gears. My bottom end is a gsr block with a ls crank/ rods with jdm p30 pistons. I'm running on a chipped p28 ecu with a skunk2 program with the vtec engagement set at 5200rpm. Timing is set at stock. The engine runs real good and throws no check engine light.
my problem is that whenever the vtec engauges the engine bogs and stalls real hard. Almost like if I hitted the rev limit. I don't understand what can be causing this. I got my fuel pressure set at 48 psi on stock injectors.

 

get it tuned

i'm going to get it tune once its fully broken in.

any other suggestions?

 

Skunk2 stage2 cams don't like vtec engagement lower then 5600 rpms, hence your problem.

Also, your fuel pressure should be at 52-55 psi at WOT on stock injectors.
