Went for a new tune today. After porting the eaton, adding big SCT MAF, BAP and 6# lower with 3.1 upper, my power and torque went down!!???
With 2.8 upper, stock lower and stock eaton I was at 440 RWHP and 470 RWT. I thought for sure I would be around 500/500 with these new mods.
The A/F kept going lean above 5000 RPM in spite of tuner's efforts. Are the stock injectors the problem?? Stock injectors should be good for 500 hp, right? I'm running the BAP at 20% but we got the same results at different settings. We added timing but backed off when we got detonation at higher rpms.
Overall disappointing. Any ideas?
