ok kinda a weird question but im just a little confused i am running a redtop sr with hx35, 850 injectors, and hks 264 cams along with all the proper suporting stuff and a power fc d-jetro and talking to my tunner he said i should only make between 250 and 300 hp. that just seems a bit low to me i have herd people making alot more with similar setup as mine if not not less. i made 310 on my rb20 with stock injectors and turbo and chipped ecu!!! just woundering if he is yanking my chain or what. they are very respectable tunner so i wouldnt think so.. i was really hoping for around 450 if ya know what i can change to acheive this let me know!

ya that sounds a bit more what i expected. i took it to garage boso i would think they are pretty respectable since they are formula d team and all anybody else got there cars tunned from these guys.
(note) im not bad mouthing these guys at all they have been super helpfull get this car brought back to good conditon and are helpin me with my engine build just curiose as to what my options are!!

i got 300hp with 16psi, 850cc, stock longblock e85 and a canned rom tune.
id expect more from your set up being fully built running more boost.

Go to koji at Driftspeed and never look back. I waisted so much money on bad tunes before I found him. And that number sounds really low to me. On koji's dyno pack (known to read low) we hit 275 at the wheels with a s15 turbo, 550cc injectors, and a z32 mafs. It actually read out 292whp on gdimentions dyno jet.

I'd be pissed if I spent all that on those parts and only hit 300
