I Did an LT4 conversion on my Vette and running E85 (E65 or so from pump), Currently running twin M15 nozzles 100% Meth. Meth Kicks in about 2 PSI and has a slow ramp to full pressure. Alky Controller at about 5 gain. I realized after the fact that one M15 was plenty and may delete 1 in the future.

I have been tuning MAF only at this point. Most of the Data I just Cloned a Z06. Injector data/torque etc...But Stock Z06 timing was causing Knock. Possibly cause LT1 Higher engine compression? Not sure - Start/Idle/Drives Perfect and its very responsive.
Last year after getting it some what tuned I put it on dyno for Just numbers and it put down 620HP/650 torque. Somewhat ugly Graph tho I am guessing my Spark table was a little rough. Hoping I have gained some since then Feels like it anyway.
Next steps VVE and Torque Tuning..... Been putting it off as it seems complicated and tough to do on the street. Anyways Check it out. Need Input Thanks!!
