thanks razor and chris (my holmie)
we did another car today
it had
Buschur Racing Ported and Coated Manifold
Megan O2 Housing
Hallman Manual Boost Controller
Custom 3" Turbo Back Exhaust with High-Flow Cat
Perrin Intercooler
Injen Upper IC Pipe w/ Intake
Niesi Lower IC Pipe
Ignition Amplifier
Walbro Fuel pump
APS BOV
before tune the car did 278whp/240wtq... at 18.9 psi tapering down...
after the tune, the car did 309whp / 302 wtq... at 21.5 psi.... it had done a little higher, with slightly more boost, but this car was slightly more knock prone than the other one in this thread.
The final tune on this one had only 1 knock count in one site in each of the last 4 pulls.... did within 2 whp/2wtq on the last 4 back to back....
I think the main difference between this car and the other one, is the highflow cat (random tech) and additional resonator and "quiet" magnaflow muffler. The other car has a full non resonated catless setup, with a fart can muffler.
i did dyno pulls on both cars in 3rd and 4th... this one wasnt an MR, so had the 5 speed.....
We will be adding wa-injenction to both shortly with some larger injectors....
both of them really haul ***, but the MR is just an animal, i think it was broken in a little more aggressively...
also, this car had a decent exhaust leak, due to a bad weld, prior to the cat and the secondary o2 sensor... I also use my wideband on the dyno in the exhaust tip, so it may have been reading a bit leaner than it actually was, so i may have been able to make a bit more power... it was about 11.3 tapering to 10.8 afr, very safe..
im going to put a full 3" catless on it, to do a back to back test in a week or so..
cheers
