I haven't messed with aftermarket injectors... yet... But TBH if it does this at cruising, I call CPS, just replaced mine for the exact same symptoms...
to me, there is not a better investment for real time monitoring than a decent scan gauge. AE is nice, and much more complete, but I will not be dragging a laptop with me everywhere I go.
I did contribution test before new PIS injector and showed no8 was low on compression ,,.. I have a blue one from RIFF RAFF .. ive read about no8 low all the time .I will change this afternoon or in morn ..
ok iv'e put 300 mile on the truck and starting to get use to custom tunes .and injectors are working flawlessly it was cps that made the stutter or skip at cruising speeds.had grey cps it wasent 2 yrs old .... thanks guys.
