so after getting my car back last night, i have been doing some thrashing.

i gained 9 front wheel kw in the high End range. vtec is where you feel this power. it kicks in hard and pulls hard. its fun as!

issue is im missing approx 7kw out of the car. my tuner was not happy.

he predicts its from my cat and headers. i reckon its from my cat and exhaust.

the car pulled 133.2kw ATW. the issue is at about 6800 rpm, the car spikes several times - it does not build any more power but just goes up and down up and down like 6 times.
so something is wrong somewhere. im going to start slowly by changing a few things.also possibly going to a single exhaust system... J's 60rs.

i believe a stock standard euro on his dyno pulls about 117 ATW.

now he believes it should be up near the 140 mark. maybe 138ish

i will first change my cat to a high flow cat. (dont ask me why previous owner didnt put one but whatever. was not my doing) i always buy stock cars and do it myself but this car was too clean to give up. lol

lets see how this goes.

has anyone used JTune products????
if so let me know!!!
