So we spent Christmas Eve working on the shop X again after a number of hours the day prior testing a few hardware and electronics products. It got late and we ran into LIMP MODE a few times which was frustrating. This was only happening at very high boost levels.
We slept on it and came back in today prepared to put our thoughts together and implement our ideas.
We had some great success this afternoon and many of our ideas ended up working out, needless to say.
Manipulating boost, airfuel and timing further optimized the state of tune.
We also reached what we feel was the limit of the stock intake filter at 30psi. We will post another thread outlining back to back pulls with and without the stock filter in place. In a nutshell the results showed peak to peak gains of 12whp with an average of 8-10whp across the powerband.
THIS is the type of test we always wanted to complete with most intakes in the marketplace affecting boost and manipulating the airflow signal in order to make their claimed gains. Now we have results that will document a TUNED Evo X with and without a filter restriction at the same boost level and state of tune.
At lower boost levels, there will be proportionately less gains from an intake on the X.
Anyhow, we'll save that test info for another thread.
For now, here is the current state of tune of the 5sp GSR with LIMP MODE eliminated. Still on factory BOV and intake pipe, stock catback, stock FMIC, pipes and OEM BCS boost control.
