how much boost

[GNational86]

How much boost have you guys run on a thrasher 108 static chip?
What do you think i can run with this setup-

Te44
bluetops
old kb big boy fm
powerplate
walbro 340 w/ hotwire
kb billit afpr
3 inch exhaust w/ultra flows
Stock d5 converter
stock downpipe

I have gone 13.13 at 104 with thrasher 92 on street tires at 18# boost no knock.
I think my lack of tuning knowledge is holding this car back. I went to track last night before it rained and only ran 13.45 at 101 on hoosier QTP 27/10.5. I put the 108 chip and the car was pig rich 869o2 with 16# boost and 6.9 knock. WTH is going on.

Thanks for any help here. Mike

The 108 chip is commanding more fuel than the T92. How much fuel pressure were you running? A 108 chip and 16 psi = pig rich. I'm guessing this was on pump gas?? Put some real gas in it and turn up the boost!

Edit: I was thinking you said an RA108 chip, my bad. Not sure about the thrasher, but never the less you will need some good fuel like c16, that chip has a lot more timing.
