My 4094R turbo has a lot of lag in it at 5800’. Correct me if I am wrong, but my understanding is that decreasing the timing table down low will help spool the turbo quicker. My question is how far out in the table should this adjustment be made (to 1400, 1500, 1600 RPM)? And at what mm3 value should I start adjusting at? How safe is it to use negative degree angle numbers?
