I have a 99 gst with a 95 ecu dsmlink v2 . Dead time is set from dsmlink at 330 and global at -47 . My car starts to miss and stutter in any gear besides first over 4K I know I have no tune in it yet I can't figure out how to do do it even tho over read forums for months, I still have trouble understanding it . My car will not throw a CEL . It flashes one time under boost after 4K . Could this be from a lack of tune? Ignition problems ? Fuel problems . The car is far from stock . I'm pretty
Knowledgable about cars in general but have never had it worked on a turbo charged car. Also my boost gauge bounces a lot it's never steady back and forth between 1-2 psi whatever amount of boost . I did a boost leak test nothing major was leaking very minimal . I did a blinder leak down test was only loosing about 3-4 % on each cylinder. The engine was rebuild 33,000 miles ago. There is no knock registering in my data log. Idk if it could be the 3in fm maf not being caliberated ? It has the maf translator 2.02 . Any ideas I'd sure apreciate them.
