i have a 94 SiR II from canada it has great pick up from low to mid rpm's but when it gets over 8000 its slow all the way to 8800 rpms i have a external msd coil pack to by pass the distributor i have a aem cold air intake dc sports header no cat and 2 1/2 pipe all the way back can anyone help if this helps i have a chip i got off e bay witch gave me a 9000 red line and activates the vtec at 4700 insted or the reg 5400 rpms

 

Ok and you are expecting a stock b16 to make any power past 8000? The reason the revs start to slow down up there is because there is no power. My sir2 b16 with stock cams stopped making power around 7600. So I will say this to you buddy, stop reving the engine to 8800 because it is pointless!!!

Get rid of the MSD and that band-aid chip right away.

Your stock ignition system will actually work better and give you less hassles then that coil pack, unless you're making like 800hp, which i seriously doubt becuase you actually thought an ebay chip would help your stock engine out.

 

yeah, no power after 7600 rpm with stock cams,

 

thanks guys for ur input im gonna go back to the hitachi distubutor but the chip i dont know it activates the vtec sooner i like that but will stop the revs at 7600 like it did in the beging

 

Those chips don't add horsepower, they just use a sky high rev-limit and dump a whole shitload of extra fuel. You'd be way safer and better off to just get it tuned. By the way, the reason it doesn't pull much after 8000, is because the OBD1 B16 makes peak hp at 7800 rpm, and is supposed to rev-limit at 8200.
