[Gmecm] '749 ECM acceptable for 4 cyl N/A applications ?

[Rick McLeod]

How 'bout a '727 out of a Pontiac '89-'90 McLaren
Turbo Grand Prix, great code to work w/ the turbo
controls, and software that would work well to manage
the bins is TunerCat. I've one of these cars, and have
modded the chip w/ this software, works well, and the
controls of the turbo are good. Uses a vacuum
modulation of the wastegate under control of the ECM
vs. mechanical plus good knock safety and retard.
Might be worth considering, if you're serious on a
turbo.
If you go w/ the '749, the '87-'90 Sunbird turbo code
might be a good choice, also, can be managed w/
TunerCat also.

Good luck, enjoy.
