Alrite first off the car is a 90 crx si with a b16a with a mild setup. Like type-r cams and a 74 to 68 mm throttle body portmatched to a ported b16 im, and more. But anyway there is msd and hondata. The hondata is a stage 3. And the sport compact msd with the external blaster coil. The hondata eliminates the rev limiter and speed govenor. Anyway though iin 1st gear it accelerates really quickly, and in second starts the problem. In second the rev limiter hits at 8k...why i dont know because hondata is supposed to eliminate this. But the car gets great acceleration but i hit the rev limiter. Then in 3rd gear the car hits vtec and stops making power at around 7400. But at around 8200 the power picks back up. Like it still accelerated through the power band but the power drops drastically between about 7400 through 8200 rpms. I have dyno graphs showing a drop of like 50+ hp being lost in this breif second. What could it be. It was dyno tuned at a well known honda shop called tempest racing. Any clue on what it could be that causes it to hit the rev limiter in second and drop power in third? TIA for any suggestions and advice.
