Its actually not to bad.. but it really depends how you drive.
When I just had the basic bolt on mods with a tune I was pulling 400-410 on full tank (BP Ultimate 98).
Right now I average about 370-380 on a full tank but like I said really depends how you drive the car
Nice, with the external gate you will be able to boost it much harder.. Engine Stock internals? Just the cams done?
Also I would like a greddy plenum, that is my next engine mod... Makes the engine bay look like SEX
