Mild turbo mod to GNX question

[Detomaso71]

I just got a stock GNX and turbo was removed for safety and ta49 added
Boost is around 16 to 18 on gauge and runs well

If I change to TA 58 or TA62 stock appearing CEA and 60 lb injector and turbo tweak chip will it feel any different than the ta49 at same boost on 93 octane?

I don't want to do Alky or any other major mods on this car
Anyone got this combo with dyno numbers on street gas?
Thx

The most hp I've seen with boost that low on an untouched engine on 93 octane is about 310whp. The air was good that day too. It made 380ish with the boost up in the high 20's on alky and converter locked. It had a chip, fuel pump, ex cutout and a/f was 11.8:1 with 17 degrees timing.

I'm sure you most likely do not put many miles on the car, so if you are looking for a little more out of it run straight 100 octane and tune the car for a little more boost. The money that you will spend on a new turbo will buy a lot of gas.
