I have a '93 vette that is about to get:

TPIS longtube headers
LE2 heads
LE1.5 cam
Ported and matched intake
58mm summit racing throttle body
no cats
accell 36lb/hr injectors

Is a PCMforless tune going to be ok for these mods? Or will it just be "good enough" until I can get it dynotuned?

My pcmforless tune is working out very well for me.

A dynotune is only as good as its tuner, so IMO unless you find a reputable LT1 tuner with good TRACK results, it's pointless.

My '93 Z went 12.0 with a PCMFORLESS mail order tune. At the time, the car was full weight, stock suspension, stock bottom end, CC305, mildly ported head car. I only picked up 3 RWHP with a PCMFORLESS dyno tune...That's how close the mail order tune was

In my case, while on the dyno they found my fuel pump could not keep up. But, you can check that with a fuel pressure gauge taped to your windshield. Many mail order tuners have this stuff nailed.
