I am trying to get suggestions on a good conservative tune for my sr20. This would be used for daily driving with some occasional sprinted driving. My future plans for the engine would be a built internals+ larger turbo(gt2871r preferably) of course suited with larger injectors, maf, ect...
But... for now i am mainly running stock and want to see if theres any good items to run a stock tune until i build the engine later on. (probably in a couple years)
here are some of the mods i have
blacktop sr20det e62 ecu
greddy fmic
tial 52mm bov
3' down pipe
aeromotive fpr
walboro 255 pump
i am also installing an innovate wideband gauge as well as an aem tru boost gauge next week (on its way here)
plus im having a shop install a competition clutch stage 2 w/ flywheel
everything else is pretty much stock(stock t25 turbo, maf,injectors,internals,ect...), so what tune if any would be practical for this dd?
i have an apexi safc2 but ive heard their garbage so not sure on using this.
ive also looked into getting a piggyback tune, rom tune, or fc power.
ive heard bad things running on a piggyback for this car, but great things on a rom tune.
dont know much about the fc power.
could you guys please fill me in on what im missing?
any other engine mods to make this a reliable dd, any more sensors? what type of tune?
i should also mention i just gave my engine a complete tune up, including new plugs, fresh fluids, new battery w/ stabilizer, quest alt. upgrade, new waterpump. so i think shes fresh for a good tune, what do you guys think?
thanks!

i think your confused so let me try to help.
1st. SAFC( super air flow converter) this manipulates the MAF signal to ecu. It adjust fuel and thats about it. No timing no other adjustments.
1 out of 10 this is a 1
2. Rom tune. These work pretty well using a burned in rom. They are sometimes a little tricky to get to work right and the support isnt very good.... They do allow you to change different parameters of the engine timing fuel pulse width Etc.
I have had good and bad luck with these. I wont run them but if it works then its just as effective as nistune.
3. Nistune/nismotronic These are somewhat similar to a romtune but they are more of a live tuner and also these two have pretty good support and are generally a good choice if your on somewhat of a budget. I run nistune in my personal car. You can adjust all parameters of the engine just like a rom tune. The resolution is generally better than a rom tune.
4. Standalone. These allow you do to basicly everything nistune/nismotronic can do AND more. They can adjust fuel maps timing and either MAF or MAP based. they have some cool features with much better resolution.
IMO
I run nistune but would use nismotronic for sure due to MAP if I had to do it again. Your not looking for enough power to need MAP so use either or.
As far as reliability is concerned thats more on YOU than your tune or your car. Change all your fluids do sparkplugs check the turbo for play check for boost leaks change the fuel filter and other general maintnence items. Thats more important that 10 psi or 7 psi if its tuned correctly.
These tunes arnt like fast and furious though. These are software programs that allow you to change certain parameters. Not a tune. Big difference.
