Don, Nice talking with you last week & I'm glad it is working out for you. R&D is expensive & time consuming to say the least. Sounds like you can drop the 160's down to a smaller injector to regain some tuning ability.

Don, I was contemplating the same thing a while back with the aerated nozzles, but the tech people selling them were clueless with respect to flows, pressures etc. Maybe you had better luck than me. If you could send me your phone #, I'd be glad to call & compare notes. My e-mail is...

sales@lonniesperformance.com I'll try to give you some feedback.

You can try setting all the cells immediately around your normal idle cell to the same # this minimizes fuel changes when the idle fluctuates. This may stabilize your idle. I'll take a look at your file if you want.

I was speaking of the ECU, not the c-com software. I believe there were a few LT1 upgrades since 2000 on the ECU. This may improve your idle quality. Why are you running open loop at idle? The charger may take enough alternator load off the motor to free up the idle. This raises...

You have proven the voltage is not consistent. I'm not sure what kind of charger you are using...... you need a serious charger that is capable of starting the car. Put it on high & it will bring the voltage up to the upper 14v range. Then see what your o2 reading is. A small trickle...

Next time the car is surging at idle, try connecting it to a battery charger. This will increase & stabilize the voltage. see if the idle smooths out. My LT1 did this & also a 5.0 Mustang I built did the same thing with a FAST system. You need an alternator that will provide stable...

Matt. Let me know what you want for your credit. I'll work with you. The LT1 is generally good for 20 plus hp per lb. of boost, so I bet you really noticed a difference. How high are you revving it now? The pulley is about as small as you can go, so short of a custom one, it will only...

Matt, Glad the new pulley helped your boost situation. You can slowly increase the timing & pick up a lot of power. I'm guessing you are currently leaving close to 100 hp on the table with 19 deg. Most LT1's will make peak power around 26 deg timing at 10-11:1 A/F range. As far as the...

All propane injection that I have seen is in vapor form. Injecting liquid as you stated could substantially cool the mixture, but the amount needed for cooling would equal a huge quantity of gaseous propane. This would be well in excess of the amount required to actually fuel the motor. It...

All major nitrous kit manufacturers offer alky solenoids. Neither the standard gas solenoids nor the notrous solenoids will not last long with rubber seats. Teflon seated pistons can be purchased to upgrade the standard solenoids. Cut the HP rating in half when considering the size of the gas...

I can guarantee the voltage offset is not correct as every injector brand/size has a different opening characteristic & the FAST box has only 1 canned setting. I sincerely hope the next version has an adjustment table like the Gen7. The present FAST system has caused me grief on 2 tunes so...

If the o2 correction was close, you should have changed the A/F table to richen the mixture, not the VE table. Give the motor what it wants to run well, not what value you think it wants. If the o2 is off, & you have to set it to 11.8 instead of 12.5 to compensate for the o2 error, then do...

Check the air filter. As simple as it sounds, after a few miles they get a slight restriction (from dirt) & will collapse shutting off the air. I have had 3 experiences with this on different vehicles. Let me know if it works.

If it is a stock regulator w/ an adjustable top or a Hypertech style it is not boost sensitive on the LT1 engine.
