Just today I had a plug foul out...so I replaced them....I feel it is because I am running too rich...well I thought I had a while before it would foul out again...well it fouled out within two hours...I really only know carbs on how to fix that. So How would I fix my TPI so I wont run so rich???

 

Get yourself some books on tuning and modifing tpi systems, they have kinds of trouble shooting instructions, then when you are reading to proceed check back in with specific questions. There are too many thing that could cause what you are experiencing for people to guess at.

 

Are you running a custom chip for your L98 swap, or the factory LB9 ECU set up???

 

I found out what the problem, was/is....I figured I should do a few things before I mess with the injection system...well I have bad news....I decicded to do a compression test on my car...well found out that it is off....meaning I have two bad piston rings. eerg!! So I am ordering a rebuild kit with performace pistons that are 0.030in bigger than stock...and then ofcorse bore out my block...so I guess its all for the better "take the bad with the good" So now I had a problem going to fix that and all my leaks....and at the same time get more power!! woohoo...
tanks anyways guy!

 

So you figure you have two bad ring sets, right?

How did you arrive at the conclusion? Tell us how you ran the test and what the readings were.
