Low Numbers on LS1

[franco802]

Hello everyone, I just purchased HP Tuners and will be doing some data logging soon. I have a 2000 Corvette with 228/230 .585/.585 112 lsa Trickflow cam, stock intake with Haltech air bridge, stock z06 exhaust system, long tube headers, ls6 intake manifold. I made 363whp/365wtq on a Dynapack. My tuner did say his dyno reads low, but many people are saying I made low numbers even on a dynapack. My tuner does do good work and is very reputable. I was starting to think my cam might be off a tooth, but I kind of doubt it. Here's my dyno sheet, sorry it does not show the afr, but I will get the tune and log soon.20181113_213520 (1).jpg

The shape of the curve looks good.

The stock exhaust and factory intake probably hold it back a little bit.

Overall it looks healthy, but without seeing spark/fuel/compression/displacement/fuel type/plug condition/etc data its hard to say how much is on the table.

Thanks for the positive reinforcement, I'll post the tune and the logs as soon as my tuner gets back from vacation. I also now have high flow magnaflow cats, Corsa Extreme exhaust and a k&n filter with ziptie mod and the haltech intake bridge.
