well in december i finished up my friends turbo ( 1994 ls) then tuned by jeff (evans tuning ) got it to 215 whp @6400 and 214 lb torque @5400 with 8psi . well now its febuary and he wants a little bit more , but really doesn't have the money to retune. my question is how much more boost would be safe without retuning ? maybe 2-3 psi ?

none at all...ur friend is tuned for 8 psi turning it up to 10 or 11 psi will give ur car the lean mixture it needs to kill itself from what i know i wouldnt do it

Correct the maps are not tuned for more boost. You can easily kill the motor that way. Your friend should have tuned with the future in mind....

I think Jeff Evans will retune the car for a lower price then the intial charge, but i could be wrong.

$200 for a retune assuming everything goes smooth... $100 for the first hour on the dyno... $100 for the second hour on the street.

What's his plan to get "a little bit more?" Swap out parts for more power? Or just up the boost?

as mentioned, NoNE, nada, NOTHING, no more boost until retune.

if he want more power, I would also recommend cam gears, and tuning the cam timing. It has shown some great results, and maybe go up to 10-11 psi........on a stock map sensor.
