Will there be any great gain in running a DP without any other mods than a HKS panel?
Would there be any downsides to fitting a DP without a tune?
While some on here would declare you must absolutely get a tune after a DP, it's not entirely necessary. Yes, you won't get the full benefits on what an aftermarket DP would bestow you, it won't blow up your car if you don't get one.
There have been quite a few people on here that have run Phat's DP without a tune for months (one for over a year) without any issues. Even I ran Phat's DP without a tune for a few weeks. Sometimes it's just hard to organise a tune in line with all your exhaust mods. So yeah, nothing wrong with getting the 1 tune at the end of your mods so you don't have to pay for a re-tune.
Even with no other mods like a centre or mufflers, you will still feel the difference. Response will be more immediate. You won't get large gains from a DP, but the car will certainly be more driveable.
