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!
