Moved. This is not a introduction thread. Please be aware of where you are posting threads.

To answer your question. You need fueling and tuning to run high boost. I suggest you read up on what it takes. It's more than just raising the boost to make more power.

Stock fuel system/ turbo at 7psi i can hear pinging up steep hills with 89. I think i should be able to do 10psi with 91 and stock cooling systems. More than that i plan on using 95 from the local track (laguna seca) until i get methanol injection.

ok thats a bit better. 14-15 with a basic home tune, though a wideband to measure to AFR would be be a good investment. if you have a pro tuner play with it you could prob run 18.

with the high compresson i cant seem to run more than 8psi.The afr's are good but need more octane.water meth injection is in my near future.At 8psi my car will spin the tires in second and when shifting hard into 3rd and i run riken 16x8s with decent tires.

Im on the stock fuel system and my car runs around 10.5 to as much as 12.7 depending on weather conditions.

Im only running 3inch exhaust and driftmotion intercooler. No boost controllers should i be worried about upgrading the fuel system? It does sem to be running really rich between shifts (Backfire's when ran hard) But i figured it was due to Vented BOV and No Cats or restrictions on exhaust?
