Alright just need some opinions, car has 1200 miles on fresh rebuild. Seems to run fine except when i get into upper rpms in boost kinda cuts out. But still goes to redline. Data logger shows some knock, sometimes as high as 20ish counts. The wierd part is itll still have 21 give or take degrees of timing advance, and the egt gauge ususlly never goes past 1500 ever. Ive tried richening it up some but didnt seem to affect it. The reason i was thinking it might be lean is the knock off 255 fuel pump, cause one night on pump gas boost controller set wuld hit 15-16. Then i put ssome 100 octane in and get on it to do a log and boost now hits 18 without me adjustying anything. What you guys think? The low egts are throwing me off.
