New turbo new tune?
So my car was dyno'd last weekend, and I was upset with the way my turbo spooled, it had a lot more lag than I thought it would, boost coming on at 4,000 not too sure where I made full boost, but it was over 5,000. But long story short I made 287 whp with 13 psi in my 1.6 with a T3/T61 non-BB turbo. The shop who tuned my car (Sound-Performance) known for there Supras said with a smaller turbo my car would make 300+ whp at 12 psi, if I where to get a new turbo would I have to re-tune the car, even at the same boost?
Here are the three turbos I can't decide on:
-GT2871R w/ T3 .63 exhaust housing
-GT2876R aka GT25/40R w/.63 exhaust housing
-GT3071R w/ .63 exhaust housing
I want a good spool, but make the most power. I know they'll all have different power bands, etc. but which is the best balanced turbo for 300+ whp?

Ok does any one esle think his 280-300 whp at 13 psi out of a 1.6 is alittle high. Even i think it is a little high. Sure y8's and airbrush did it on there NB's but who else has seen a 1.6 hit numbers like that before. Please jtothawhat post up a sheet on this i gotta see it if it is true i will most def look into a huge *** turbo. And try to figure out what you are doing right.
