2017 Mustang gt tuning problem

[Grimreaper]

Bit over 400whp sounds normal for intake and tune on 91/93. Look up the motoiq pp1-3 tests and dynos. On 91 your prob not getting more than 22 or 23 degrees of timing I'd imagine depending on alt/humidity. Maybe less. Post a datalog of a 3rd gear pull.

Ok. Just going with what the tuner is telling me ,that somthing is not right. This is my first car I've done any work to so still learning.

You need something to log with otherwise any changes will go unnoticed.

8 degrees being pulled should feel like a dog though. Assuming the tuner read it right like previously mentioned.

Add octane via boostan/torco and dyno again. But quick street pull while logging would suffice to. The way the timing curve looks can shed light if it's real or false.

If it's still showing with a healthy dose of octane, time to start checking for rattles/loose exhaust like cory mentioned.

Awsome. Thank you. We did put a bottle of octane and nothing happened. I guess I'll start looking for rattles.
