I had a thread going a few weeks ago about how I just barely beat a stock SRT-4 with my:

Streetport, 3mm seals, non-seq turbos, M2 large smic, 1200 secondary, walbroh fuel pump, dp, mp, exhaust, intake, unorthodox pulley, and apexi pfc tuned by rx7store

The problem then was that the car was breaking up badly under heavy boost and throttle.

Swapped out the coils and bam problem solved. The car runs a zillion times better but im still running crazily rich!! My friend was following me on the highway and he told me on the onramp when I got on it thick black smoke came out.

I had a manual boost controller that stopped working and just bridged the line, Im getting decent boost however it fluctuates a little between 9 and 10 pounds. I have a profec b coming I just got from a member.

What can I do to lean it out a little?

 

You can't knowledgeably lean it out, without some sort of Wideband. I would wait till your boost controler gets to you and take it back to a dyno.

 

^thats what i would do, control the boost and get er' tuned. you should be able to up the boost if thats all it is.(while tuning of course)
