Does anyone here in the forums have any input on the JET performance products? What type of gains can I expect. Will it harm my car? Will it make my car illegal? I am attaching the link to the JET site. Any opinions and expertise is welcome. Thank you for your assistance.

I was wondering, has anyone seen chips which reprofile the vtec mappings and fuel maps?

I thought it would be kinda nice to have vtec roll in at 4500 or 5k.

 

vtec engagements that low wouldn't work to your advantage. dropping it 100 or 150 rpm's that would be about it.

not sure on the chips - I would assume they are similar to plugging in a vafc and having static settings for you. which can be 'ok' for the dollar, but not tunable for your use, nor tunable to your environment/altitude.
