Sputtering with ses light flickering

[QUIP'6']

Cars been running beautiful until yestrrday . When I drive around it round great until I go wot. Currently running 15 psi. No knock, fuel is up to snuff and coil pack and module new gm. When I go wot it sputters and bucks and the check engine light is flickering but pulls no code. Is this an electrical problem?

yep. Could be the + batt cable on the dp.
Could be the - strap loose under the turbo.
