335i vs 5.3 nova 335i: fbo minus inlets on a e70 mix..Map7 which spiked to 21psi and was at 16.2 by 6000.
Nova: 5.3 swap, carb conversion( 650dp holley, edelbrock dual plane), headers, 243 heads ( milled for more compression), ls6 cam, 3.73 gears, 2800 stall, race gas and 150shot?( 63/73@6.5psi, but was down to 5psi psi on these runs) using a nos cheater plate 8 hole, bottle was at 1100psi.
First run i had 1st gear set to 15.9psi and as soon as it shifted to 2nd it spiked and boost fell off and come back on.
2nd run i limited boost to 12psi and had no issue.
Gonna go back to 2nd gear launches with full boost.

Nice runs, modern turbo bmw technology has came along way. They have definitely earned some respect.
Are you having a problem regulating? Or is it just how it reacts turned up like that?

It only has the issue when i launch in 1st gear and shift to 2nd. It spins 1st no matter what, so i pulled it down to 12psi to limit swheel spin and the boost spike. The jb4 helps likot it as well, but not enough.
