Hello from another new (old) guy

Have a current project that I will need to tweak the tune on a TBI unit. 88 chevy silverado with 5.0 liter /700R4 trans. The engine is basically stock with the only upgrades being headers, true dual exhaust and hydraulic roller camshaft.

The engine will start and idle but eventually stalls out as it gets closer to closed loop mode. I am new to tuning but always wanted to learn and hopefully now I can dedicate a little more time to do so. Have been researching over the last few

nights what options are available for these OBDI ECU's and I very impressed with this forum at the content and knowledgebase. Looking forward to being a member.
