However, I switched to it a few weeks ago kept it for sometime and logged. Had some knocks at no/low load (which can be normal) and can also be because the HPFP is not properly tuned, as the car even has the "hiccup" feels from time to time when using the OTS map. I spoke to TTFS at the time about it (noise & hiccups) and they said its normal, it just needs to be properly tuned, which was done on my custom map.

Interesting, and good info.
Does TTFS have any input on the knocks? They're going for pretty high boost in their tune.
Have you ever done a dyno run just to see what relative numbers you're putting down, which may also point to the custom tune?
I'll be going thru all this soon when I install a Dorch HPFP and begin running half 93/half E85 and do a custom tune with Halim.
So, just throwing out questions. |
It was not tuned by TTFS, but I contacted them after installation of the pump when I heard the noise. (I thought it could be tune related but called for reassurance)
Yes it was dyno tuned, however, the numbers can be irrelevant as it was a Mustang Dyno and I don't think any M2 has been on that dyno. + I don't have a 'before' figures.
Apart from the knocks, the car pulls really well. I'm satisfied with the performance but I'm worried about the knocks because I care equally about reliability. A negative point from the boost is the fast build-up of IATs.
