I heard the 2650 is more efficient and a little better but will not be as good as a whipple gen3 unit. I’d still have to spin it hard to make the boost to make up for the compression ratio.

Sorry if this is in the wrong spot. Here’s my issue: I have a built motor coyote on 10.45:1 compression (robbing me of power) and I’m pretty maxed out on my current setup. My 2014 GT with Roush 2.3 has a 69mm pulley, ported elbow, whipple twin 68mm TB, Pmas cold air, Kooks headers/high flow...

Update: I fixed the issue with headers lol for some reason after doing a header install the code went away and never came up again. Exhaust leak somewhere maybe was causing it and when putting in the new exhaust everything was re-tightened and buttoned up. 02 sensors were a little lose as well...

Update, so I re-checked everything. Plugs are all good, had a shop look at everything and they say it all checks out. Put it on the dyno and Air/fuel all looks great. I did some data logging and ran through the logs, short trims on bank 1 and 2 look decent. At WOT 6900rpm, bank 1 is at .99 and...

I dropped to an 85mm pulley from the 79mm pulley and it still was having the misfire issue

Yes I have multiple datalogs that I sent to Lund Racing, Jon jr. said its a lean misfire and thinks its the injectors. I've checked to make sure they are seated and everything seems to be working fine. If they weren't seated correctly I'd think it would be showing more of an issue at any rpm...

I'm not sure how to check that honestly, was thinking about taking the car into a shop to have them check the whole fuel system.

What is FPDC? I'm running 2 step colder NGK plugs and gapped at .028 The car was running great and everything was good. Took a trip to vegas, came back, few days later was doing some pulls and everything was great. Few days later was doing some more pulls and it started to have the issue.

So when I'm driving my car, when I go WOT and over 6500 rpm's my car starts to flash the check engine light and its a p0300 code. I check my misfire data through a handheld I have and I have misfires on every cylinder as follows (cylinder and number of misfires): cyl1-8 cyl2-2 cyl3-18 cyl4-1...

okay thanks guys

Hey guys new to the forum, but been on here for info a lot. Used to own an 03 termi but anyway here's my question. I have a 2014 Mustang GT with the following- -2014 Mustang GT Block (10.45:1 compression) -MMR 1000hp kit (forged boss crank, manley rods, manley pistons with ceramic coated tops...
