  2. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Log looks much better after running the car as hard and as lean as the last log make sure you check those plugs. Id say this is definitely a 20+HP jump over the dyno run for sure.
  3. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Jesus this is a big oops on that BEF... Fuel trims maxed out, Throttle wide open, AFR 17:1++ F Me.
  4. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

  12. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Ive done quite a bit of these. Its honestly sick. Imagine proper fueling at 24 PSI on E50 and trims at 25 on the JB4. Its a shame alot more people dont go this route.
