Sill,
How many base maps are there on a PFC? Are they good enough on a mild modded car without dyno tuning? Is it possible to street tune my car using the hand held commander?
Only one base map, just so you can drive the car under normal conditions untill you tune it for your set-up.
Yes , many guys street tune w/ the commander, it's just a pain in the a$$ ,and your limited to only changing one cell at a time vs. blocks of cells with the Apex' software, but it's done all the time.
At the end of the day reguardless what you end up getting, Rom-tune, PFC, E-manage, etc.....a tune is the #1 spot you sould not skimp on.
I've seen several cars w/ all sorts of crazy mods' get left behind by cars with basic mods and a good tunes b/c they half a$$ on the tune.
If $$ is a issue , street tune w/ the commander then when you get some more $$ have some one with the Pro' software tune it on a dyno.
Remember your mods' are only as good as the tune behind them.
