    E85/Flex Fuel VT numbers!

    Not using HP Tuners but it would be doable with it as well!

    E85/Flex fuel for the win!

    This was E50-E60 fuel in a VT with stock engine, stock turbo, and stock catback still on the car!

    18 psi boost to make these numbers..... 257-265 whp SAE cf. Stock tune on 91 did 178 whp SAE cf.

    NGK race plugs(R2556B-9) looking good as well!

    Did you make it a true flex fuel tune or was it just adjusted to e50?

    Tune for E60 fuel trim and afr wise as that's the avg content of the fuel and runs fine a decent range in either direction. Timing setup a little conservative for E60 so it will run fine on lower E but will still pick up power on higher E. Boost/load setup to not make too much power for the given mods on the highest E content. Also setup to maintain boost/load up to 5-6k feet ASL.

    If he wants to use 91 in his area it takes 3-4 mins start to finish to flash another tune in the ECU already made for the car.

    Not sure where power is at but on E80 tested fuel with 18-20 psi stock turbo and not even FBO 40-80 mph in 3rd gear comes in less than 4 seconds! And I get tire spin at 40 mph trying to make the pulls!

    So traction was limited on the 225 all season tires and stock suspension but on the last tune it did 13.421 @ 105.57 MPH on E80 fuel! To make it even better I had no weight reduction, not near FBO, and the throttle cut 3x during the pass.

    Getting all this sorted over the next few weeks and hoping to be in the 12's at 110+ MPH on the stock turbo and stock engine. Not sure if this is doable as the transmission is on the verge of slipping as it is now.

    if you are not going to a dyno you are going to need some good tires on that car to see how much power its trully making

    Tire is not my issue, suspension is, which is being taken care of on 5/5. :-)
