Hey guys,
I recently rebuilt my 6 bolt (w/ 7 bolt head) with forged rods and pistons, 272 cams, oversize valves, dual coil valves springs etc. The motor is mounted on solid urethane mounts, and I am running 1 step cooler plugs. I have around 700 miles on the build. The turbo I am running is a T04E (67 trim).
I'm not sure how many people are experienced with Ceddy mods, that is the way I have been tuning my car. I'm currently running the same tune that was used before the build and the car ran really good. And the car runs good now under easy driving conditions.
I have just started trying to get into boost and something I have noticed quite a bit even under easy driving is that my CEL occasionally blinks on and off for a few seconds. This is supposedly a sign of knock according to the way Ceddy mods is set up, but perhaps it's phantom knock due to my cams/ motor mounts etc.
The actual issue:
When getting into the throttle, the car builds boost fine but does not produce any decent power, it accelerates, but rather slowly. I have had both boost leak issues and exhaust leak issues in the past, and this seems different.
My question is if anyone thinks this could be the computer pulling timing due to phantom knock, a similar issue, or something different entirely that I may not be thinking of. I plan on moving to an AEM pretty soon, which may make resolving this issue easy. Beyond that, I have no idea where I should begin to confirm or eliminate this possibility.
Any opinions/ help is greatly appreciated.
Thanks.
