| Ben Tyson's 1994 Twinturbo Ben came in for a Nistune ECU upgrade, white face gauge installation, fix a squeaky belt, boost leak test and DYNO TUNE!!!! Initially at 13~psi it there was a ignition misfire Dane Miller pulled the spark plugs and gaped them down from.042 to .034.. Base lining at 340 whp on the stock Z1 epprom chip, Dane pulled the eprom and installed a Nistune real time board inside the ECU in place of the z1 chip. From there on out the tuning was a breeze. Increasing boost setting AFRs and dialing ignition timing power was raised to 440 whp. From 15.5 psi to 17 psi there was no gain on this one, so it was left at 15.5#. None the less, not to shabby on pump.. Ben sports:
