So here is my setup:

Greddy TurboKit:
TD05/TD06 18G turbo - Internal Wg
720cc Injectors CPR Racing
Precision Intercooler
2.5" Downpipe + Exhaust
NGK ZFR7F-11 Plugs
255lph Walbro Fuel Pump
Greddy E-01 Boost controller, Boosting about 10psi
and for tuning Im running on uberdata.

Here is my dynograph


On the dyno, I did third gear full throttle, As you can see on the graph around 3500 rpm my car starts to misfire! Before i got on the dyno, i put brand new spark plugs in. After getting off the dyno, I cant seem to get any power, nothing in the high rpms. It just bogs and doesnt want to go any higher, espically at 5000 rpm. I'm only getting a little under 200whp. I should be atleast around 250whp.

Any help would be great guys, If you need more info let me know.

Thanks

YOU SHOULD BE WAY HIGHER THAN THAT WITH THOSE MODS...
  1. Recheck your timing, you may be having problems with Vtec timing also.
  2. Check your fuel
  3. Also you must verify your ECU settings

My favorite ECU first choice is Microtech then AEM you cannot go wrong with these.

From what I've read, you shouldn't gap spark plugs. NGK's come already pre-gapped, and I guess gapping them can cause inperfections (the tool that is), which can lead to them not functioning properly. I doubt this is the problem, but I figured I'd throw it out there

yea for stock cars.......spark gaps for aftermarket boosted cars dont follow that.


get something to check the gap on the plugs and report back.
