alright i got a 94 del sol with a obd1 gsr swap it is bone stock except for an intake and cat back. i am having problems with the power out of the motor.. it has a bonestock gsr ecu in it and it looses power after like 6500 rmp almost like its a single cam ecu but its not i am sure for that cause i took my friends out of his gsr hatch and it is doing the same thing and i also have a chip for the rev limiter to 10000 and it still will loose power after 6500 and it dosent hit a rev limiter. it has plenty of oil and everything like that... i had a gsr in my hatch and i could rev to 8500 all day long and it was great. does anyone have any ideas what it could be??
