Beaumondt,
Your too polite haha
I swapped my stock cooler for a truck core. Now if people don't like truck coolers, I can tell you its better than the stock one.
I gained around 20rwhp from cooler upgrade. Admitedly a lot of that was in the piping as well. But that is part of the cooler upgrade.
Now No doubt Rev210 has done well with stock core. End of the day its one example though. I don't know where else he has spent time, on tune, timing etc .....
Its a the standard mod's that are known to work well. Cooler, Zorst, Boost. They are Best bang for buck really. There also safe mod's for people not to sure on what there doing.
Rev210, nothing wrong with the Mod path you have taken.
ITS JUST WEIRD
