I got my car tuned at Blankenship Tuning and Performance today on 93 octane and tried to on E85. My 93 octane tune was great....made 649 rwhp and 560 rwtq on 19 psi with 18* of timing and a conservative tune since it was high boost! I thought that was great! We tried to on E85 but I gotta get a boost a pump to help the pumps out a little since the pumps could use a little help witht eh E85 fuel demand..haha.
