Careful before anyone jumps into upgrading software. I heard (true or not), that if your car has (random) power loss issues, with or without CEL on, get that resolved first before getting into software performance upgrading. Will a performance software upgrade address the power loss issue? No according to doubters and naysayers out there.

So get your ride in tune firsts, otherwise you'll end up worst than before and see your hard-earned money down the drain twice. one for spending the money on the performance s/w upgrade and second to spend the money on the original problem (random intermittent power loss) which may require a factory (not performance) software upgrade and/or new maf, crankshaft sensor, etc.

Above applies not only to e36.

True or not, anyone?
