T34.55 to T34.63
If i change my turbo from the T34.55 to a T34.63 how much extra power will i gain with a remap.
My T34.55 peaks @ 28psi and holds 22psi @ 6500rpm

Have you checked which pressure the actuator opens at, had this problem b4 with a brand new actuator, screwed it all the way up and it would only do about 15psi.?

My old 3dr with a T34.48 Peaked even @ 32 psi and held 28 allday long after Karl had mapped it, was a real punchy car that though, miss it too...
Edited to say,
Martin,s old saff made 391bhp with a .63 on peaking @ 33 psi holding 28....

Was all checked over by MSD in Decemeber and the only leak was from the dump valve which has now been replaced.
The figures shown are the max MSD could get out of the turbo.
