So this is my problem, i did a mini me swap on my 92 dx (D15 Buttom) with a D16z6 vtec head the Rpm rev limit was around 5500 to 6000 and i didnt like it, so i bought a d16z6 buttom put it on, chiped the ecu (spoon) but guess what rev limit is now like 6200 rpm's and i know that a factory D16Z6 goes around 7300 Rpm's, Spoon is programmed for 8500 rev limit and vtec is kicking at 4800 and yes the vtec is working properly, i also try on a mugen chip but the rpm's are the same. when i did the swap with the d15 buttom the valve lash i did was .20mm intake .25mm exhaust... Whats the valve lash on a D16Z6??? When im like on third gear and the rpm's are around 5500 (about a 100 mph) and you punch the gas it feels like something is making the car lose power... any help thanks...

dynamics..thats why you lose powa
. 3rd gear at 100mph...sounds like need a dif ecu
what ecu are you using?
get it tuned...yeah i know you aint got a turbo etc. but a tune can give you more powr from a stock motor...sumtimes

open it up and see if its burnt up
any CELs?
is the motor stock? or aftermarket parts, like intake manifold, injectors. etc
