Help....Car Starts Shuddering at WOT

[1998gstmaniac]

Wazup, I just Installed another 14b on my car and i go to test drive it and when I hit WOT the car starts to buck back and forth when the boost guage goes anywhere past the 0 mark.I checked for Boost Leaks but can't find any. i was wondering if someone could help me out.

Would that be a real boost leak test or a visual inspection?

it was a real boost leak test.......but I solved the problem anyway...I gapped my sparkplugs down to .28 and it took care of the problem...thanks
