I've got a td06 20g 8cm and cant get rid of a boost spike, has a 6boost manifold, had a 38mm tial gate now has 44mm tial gate, exhaust is 3inch straight thru, has anyone else experienced this problem before, my tuner told me at the first tune the manifolds are TO GOOD so thats the reason i upgraded the gate. it boosts to 1 bar then spikes to about 1.5, was going to 2 bar before gate change. would going bigger again fix this problem?
