I installed 8.1 injectors in 99 5.3L. Standalone harness. Upgraded fuel pump +58PSI, I started up engine and scanned it, popped a code (P0102) Mass Air Flow Sensor Circuit Low Frequency, Already got new MAF and checked these connections.
Many numbers appears on Manifold Absolute Pressure (kPa) x Engine Speed table, what I need to do copy and paste on VCM Editor? LT B2 seems very high +25. Any tips would be great appreciated. Am first time with HPTUNER, currently researching and learning new to HPT.
