Default my mods... is software even worth it?

Hello all... i have done some research and haven't really found anything very definitive on this topic...

Current set up...

M50 manifold
K&N Cold air
Dinan Exhaust

pretty much just the basic bolt on's

I have read many threads that state the stock ECU will adapt and its good enough etc...

I know that if I did get software it would not really make a huge difference. I guess the question is are the older of the shelf tunes worth getting? I do lean towards Shark because i can switch it back to stock which is attractive, but then i have also seen TRM and Epic that seem to account for the manifold and supporting mods but i have to send the ECU to them and can't go back to stock unless I purchase one of there 100 + dollar cords so i can hook my laptop up to it and then switch back to stock for smog etc...

anyways the goal for the car is spirited driving/weekend car.... is it even worth my money to get a tune or just leave it alone? not sure i'd ever go the FI route or even cams.....

Is it an OBD1 car?

If it was me I would get a tune but I would also upgrade the injectors at the same time to get your best bang for the buck out of the manifold/tune.

A tune will always improve the drivability of your car even if itís stock.

Have you looked at RK-Tunes?

A good dyno tune is worth it. I picked up over 10whp with a custom tune over a Shark injector. Only mod was the m50 manifold and ACS tb delete. Stock airbox and exhaust. (231whp total)

Dyno tune will get you peak power if you want it but an off-the-shelf will make the car run properly.

good point... i am inclined to just Shark it..... its tried and true and can go back to stock easily if I want to

I guess i was more just wondering are those old shark and AA and Dinan tunes that were developed nearly 20 years ago out dated to the stuff that RK tunes and Epic are doing?

i can't imagine one tune is that much better than the other when you are looking at "off the shelf" versions

I have RK and itís pretty user-friendly to go back to stock if you want but the big plus side is heís actively tuning E36ís so the support is nice.

I would use a tune designed for the S52 with M50 manifold and raise the limiter to 7000.
