Only numbers I got was 250whp @ 7rpm if I remember right( they still havent emailed me the dyno chart yet). We got the A/F down under 12 but idle was starting to run rich and at WOT was still running lean(higher 13's), so the session was cut short. He said that everything chartwise looks good if only we can flatten the A/F at WOT. He then suggested a VAFC to flatten that out.

This is very strange to me cause I have not heard of the CTSC kit running lean with the stock pulley at all. Thats why I kinda just put off the engine management till I was gonna run over 7lbs. I've checked the vacum tube from the FMU, no leaks or cracks. Plugs are only 3wks old(NGK 7173's) so they cant be bad, but I'll check just to make sure tomomrrow. Only thing lefted is bad fuel pump, bad FMU or clogged injectors. Whats your thoughts?

 

Install the $15 fuel pressure meter on your fuel rail to see where your fuel pressure is at. There is a DIY in the under the hood forum.

Well, I held off on that since I had the gauge already but I guess I should. It's convienent.

 

IMO when using the FPR that comes with the CTSC kit a fuel pressure gauge is a must. This will allow you to know for sure where the adjustment is on the regulator.

 

I was planning on making several videos tonight
