slickrick, any difference with the hiflows with the tune?
and according to the chart posted on pg1, motordyne posted more gains with the combination of bolt-on's .... did you get a tune between each mod or all at once...i assumed all at once. curious on how your combination of Mods responded compared to Motordyne's advertised graphs.
I didnt catch if yours was a g35 or a 350gt, and DE or HR ?
Ive got a g35 sedan...DE. With the DE alot of mods seem to be hit or miss, but ultimately the overall health and environmental conditions of the motor would determine how well the mods respond. So in your case, the environmental conditions of the UK is bit different from the states. I can tell you on warm days here, my G feels sluggish compared to a cooler morning. In the states i drove it from NY to TX and all parts inbetween. Overall i feel like it pulls a bit better here in the UK...but ive never had a tune. In the states i had JWT pop, coupe midpipe, and HR OEM cats. I think the HR cats are a bit less restrictive than the DE..but i could be wrong. Car definetly improved.
October i installed a ISR Y-pipe, and a custome stainless 3'' to resonator and from the resonator to the backbox was a short 3'' to 2.5'' inlet of the backbox. Car definitely pulls harder, but i plan on adding the plenum spacer and possibly decat or hiflows....but id like to see your gains. I have 160+K on the clock..for a 15 year old car i choose my mods carefully to maintain drivability and reduce strain on the motor.
