I know several people with the SUN unit and they all love it. Not a single issue so far.

 

I have had my HKS DLI-II for about 1.5 years, it works great. I was having ignition break up at 26 psi, this cured that and my idle has improved drastically with the HKS 280 cams.

 

I have had both in my car back to back and there is no question. Hks all the way. The sun didnt seem to help around the 27 psi mark and the hks in my car has seen 35 with no issues. Probably close to 600 whp with no issues. There is no way the sun could do that.

I hope this helps the p0300 misfire problem.

 

HKS was no good for me , I had to go with BR CDi for no worries
