Hello gents ,
I was planning to buy this plug and play unichip ,
But I don't know if it will improve my HP , since I have install :
Piston 0.50"
AFE catback 2.5"
AFE header 2.5"
AFE air intake 2.5"
Intake jeep xj 2000
Adjustable regulator at 49psi
Injector Siemens deka 24lb/HR

This is the link for the specific unichip am talking about https://www.vividracing.com/catalog/unichip-plug-and-play-ecu-system-jeep-40l-9296-p-128764.html

So with these minor modification , will the unichip piggyback improve the engine HP or not ?
Did anybody try it before ?

Please advice

And thanx for reading
